15 "Rules" According To Sheldon Cooper

Sheldon Lee Cooper is the man-genius on CBS' Big Bang Theory. Although there are thousands of characters on TV these days, Jim Parsons' character, Sheldon Cooper, sets himself apart from the rest with his scientific whit, awkward personality, and unusual social norms. And although he—at times—comes off a little rude and insensitive. He seems to always win us over with his secretive big heart and Texas charms.

One of the things we love to hate about Sheldon is his insane list of rules that he forces everyone around him to follow. There's the roommate agreement - a contractual agreement he has with his best friend - and then his obsessive-compulsive disorder forces him to have designated meals and activities every day of the week. Which, of course, leaves his squad having to do the same. But as we continue to watch Big Bang Theory for the past 10 years, we can't help fall for this smarty pants. Here are 15 rules that Sheldon lives by (and forces his friends to do the same...if they haven't told him off by now).

15 Don't Forget Your Manners

Sheldon is a southern boy through and through. He was born and raised in Galveston, Texas, where his mother still resides. And since Sheldon is a die-hard momma's boy, his well-bred manners are engraved in his personality. The one rule that seems to pop up in every episode is to offer someone a hot beverage when they're feeling low. Which, if you think about it, is actually an amazing gesture. A hot cup of tea, coco, or coffee feels like a warm hug in times of sorrow. It seems like he's always bringing over a put of hot water and honey to Penny's apartment or to Leonard's door.

Sheldon can be a tad eccentric, but his heart is in the right place. Who wouldn't like to be offered a warm cup of tea after a rough day of work or an argument with a loved one?

14 Takeout Restaurants

Does anyone else get insanely hungry while watching an episode (or a season if you binge watch on Netflix) of Big Bang? It seems like in every episode, the gang is chowing on pizza, Thai food, or snacking on popcorn. And trust me, it gives me some serious squad envy. However, Sheldon still has his rules when it comes to food. Every Monday morning, Sheldon has oatmeal for breakfast. Don't even try to make him French toast, because he'll toss those fluffy pieces right in the trash - that's how serious his rules are. Monday nights are reserved for Thai food, Tuesday nights are for dining at The Cheesecake Factory, and Thursdays are pizza night. He also likes his chicken diced—not sliced. He eats cereal with 2% milk, and only eats chicken and stars when it comes to soup (which must be served at 180 degrees). That's one picky eater!

13 Section 8C

You're probably wondering what 'Section 8C 'stands for. Well, it's a section in the roommate agreement between Sheldon and Leonard that says "roommates shall give each other 12 hours notice of impending coitus." Luckily for Sheldon, Leonard isn't exactly a ladies man who has one night stands weekly. So this rule shouldn't have been too much of an issue except for the fact that it's weird AF! What if Leonard went out that night and found someone he wanted to take home? He wouldn't be able to have her at his place because he never gave Sheldon a 12 hour notice. And if you're thinking Leonard could just sneak inside - think again - because Sheldon usually waits up for Leonard's arrival so he can sleep soundly. Leonard puts up a lot with Sheldon's shenanigans, but if there's one person in the world meant to be Sheldon's roommate - it's him.

12 Pets Are Allowed...Sometimes

Don't you wonder why Raj is the only one with a pet on The Big Bang Theory? I could totally see Sheldon with a gold fish or even a cat hanging out in his apartment. Unfortunately for any pet lovers, Sheldon has a strict rule when it comes to pets: "Pets should be limited to service animals; such as cybernetically enhanced helper monkeys and seeing-eye dogs." Sorry Leonard, if you want a pet, it might be a little tough finding a cybernetic monkey in California. However, there was an episode in season four where Sheldon and Amy go through a relationship rough patch and Sheldon gets a whole lot of cats to replace her. If you're wondering why it's okay for Sheldon to ignore his own rules, it's probably in the roommate agreement somewhere.

11 Leonard Must Drive Sheldon To Work

If you worked with your roommate, it only makes sense to carpool and drive to work together every morning. You can save a lot of gas money, miles, and time circling around for a parking spot. However, Sheldon Cooper doesn't have his drivers license which means Leonard has to do a lot of the driving. In an unnamed claus in the roommate agreement, Leonard is contractually obligated to not only drive Shelly to work, but to his appointments and various activities. And as you can see by the scene in the photo above, Leonard doesn't necessarily love this duty. I mean, he doesn't even let Leonard listen to the radio because he doesn't want the neighborhood to think they're gang members blasting music on the streets.

10 Bed Time

If you couldn't tell by now, Sheldon is a man of many habits. And one of those habits is training his body to be on a strict schedule. For starters, he is on a timely bathroom schedule where he only relieves himself when it's his 'scheduled time' to do so. And if you think that sounds nutty, imagine living with the guy. Because Leonard is obligated to follow the bathroom schedule as well. But another rule of Sheldon's is having a steady sleep schedule by going to bed between 9-10pm. And once that time hits, the roommate claus states, "no 'hootenannies', sing-alongs, raucous laughter, clinking of glasses, celebratory gunfire, or barbershop quartets." Which translates to: everyone needs to leave the apartment except for Leonard at Sheldon's bedtime.

9 You Can't Sneeze In Front Of Him Without A Dr's Note

As a Doctor of Science and Philosophy, Sheldon knows the ins and outs of the human body. Which is why he practices good hygiene every chance he gets. If he's not washing his hands often, he's discussing the cleanliness of Penny's bathtub and making sure the entire area is clean before he hops in the shower after Leonard. There have been multiple episodes that display Sheldon's intense desire for a clean and healthy space. Which is why when girlfriend, Amy Farrah Fowler, got sick, he swabbed for cultures in her cheek while she was sleeping to make sure her illness wasn't anything serious (Ha! Can you imagine?). There was another episode where Raj sneezed at the lunch table and Sheldon made him leave and to not return without a doctors note.

8 Every Wednesday Is New Comic Book Day

Has anyone else noticed that Wednesday is designated as 'new comic book day' but it's also Halo night? Hmmm...

Another one of Sheldon's rules is he heads down to the comic book store every Wednesday to buy a new comic that he doesn't have thus far. The only problem is, Leonard typically has to drive him; which leads to the entire gang riding along and has now become a weekly hangout for the crew. But Sheldon isn't just a fan of comic books. He scopes out costumes of his favorite characters, video games, action figures - and pretty much anything else that screams fantasy/science-fiction fandom. Though we may laugh at Sheldon's interest in the comic book world because of his age, he's not alone in this hobby, and his rule for 'new comic book Wednesdays' has formed a precious man-to-man hangout for the four guys without them even realizing it.

7 He'll Never See A Movie Alone

Honestly, can we blame the man? Seeing a movie alone kinda sucks. There's no one to lean over and laugh with. There's no one to ask questions to. And there's no one to share an XL bag of popcorn with! So since this is a rule of Sheldon's, we can't be too hard on the guy. But when he does go to the movies, he goes all in. "A movie experience must include Red Vines (not Twizzlers) and Icees (not Slurpees). Additionally, he will only go to the movies if someone comes with him, so that they can perform the Hemlich Maneuver." See, you guys! This little rule has nothing to do with being alone - it has everything to do with safety. We can't travel or go places alone because then who would help us when we're choking on our popcorn?

6 You Might Think Twice About A Sleepover

It's kind of crazy that this group doesn't live together or at least live in the same apartment building. They're together every night of the week... they could save so much money on rent and gas if they just paired off into roommates! That is until Howard got married.

Since Sheldon lives with Leonard, Penny lives across the hall, Amy Farrah Fowler lives a few miles away (well, used to anyways), Howard and Bernadette are shacked up, and Raj lives alone - if someone wanted to stay the night at Sheldon's pad - they're gonna have to think twice. No one can stay the night without proper blood work and will have to go through safety precautions before crashing. This includes knowing where the emergency exits are and taking a CPR course. Even though there are two bedrooms and Leonard is usually at Penny's or vice versa - Sheldon will not allow anyone to stay in Leonard's room. Nope, any guest must use the couch. Hmm... After some thought, maybe this is why no one wants to live in the same building as Sheldon...

5 He Knocks Three Times

Even if you're not a diehard fan of The Big Bang Theory, we've all seen the clips of Sheldon knocking on someones door three times. And by three, we really mean nine times:

(Knock, knock, knock) Penny? (Knock, knock, knock) Penny? (Knock, knock, knock) Penny?

Although this habit is rather annoying, his reasoning for doing so makes perfect sense. As a kid, Sheldon walked in on his father with another woman. After being scarred by what he saw, he now knocks three extra times to give whoever is behind the door extra time to "get their pants on." Poor Shelly! That's traumatizing for kid. But it's a moment that we can't help laugh at every time he does it. And since it is a Sheldon Cooper rule - if his three knocks are interrupted, get ready for him to do the whole thing over again.

4 Someone Needs To Sing Soft Kitty

Considering The Big Bang Theory has been streaming for 10 seasons, we have seen a fair share of sickness on the show. But nothing is like when Sheldon gets the flu. He morphs into a little kid who is lost without his mommy and needs to be catered to throughout the day. Which can annoy Leonard, but he usually obliges. But one thing that is sure to make Sheldon feel a little better is the a little song called, "Soft Kitty." He requests someone to rub his chest as they sing, "Soft kitty, warm kitty, little ball of fur. Happy kitty, sleepy kitty, purr, purr, purr." And whoever is doing the singing better add a little pep in their voice or else Sheldon makes them sing the whole song over again.

3 His Hot Chocolate Rule

Sheldon Cooper has a hot chocolate rule. Finally a rule that rocks! Truthfully, this is a rule that everyone should abide by because hot chocolate should be consumed in more months than just December. His hot cocoa rule is he can only drink it in the months that have an 'R' in them. So that's every month except May, June, July, and August. And who wants hot cocoa in those months anyway? Once good weather hits, all we crave is some lemonade so his rule is quite valid here. And if you're wondering about the hot beverage rule in number 15, hot cocoa is definitely an option to be consumed - just not coffee, Sheldon doesn't do coffee or caffeinated beverages. Just tea, hot cocoa, Diet Coke, or sweet tea.

2 Three Strikes And You're Out

Sheldon comes off a little strong, but he has a good heart when you get to know him a little better. His rules are absolutely ludicrous but there is a deeper root behind each rule and why it matters to Sheldon. So when someone pisses Sheldon off, he doesn't forget it. (Hey, with an IQ of 187 and a photographic memory - it's hard to sneak by Sheldon without him saying something.) Since he has such a small circle of friends, he makes sure they're good company to keep. Which is why he gives them a 'three strikes and you're out' policy. What happens when you get three strikes? You need to take a Sheldon Cooper exam that is also accessible online. And in case you're wondering, there's an episode in season two where Sheldon announces that Penny has two strikes against him and she'll have to prove her friendship and loyalty if she wants to have those strikes removed.

1 Don't Sit In His Spot

Finally, the number one rule for Sheldon Lee Cooper! When you are in his apartment or in his presence, you do not sit in his spot. His "spot" refers to his spot on the couch in his apartment. Why is this spot so special to Shelly? "In the winter that seat is close enough to the radiator to remain warm, and yet not so close as to cause perspiration. In the summer it’s directly in the path of a cross breeze created by opening windows. And it faces the TV at an angle that is neither direct (thus discouraging conversation) nor so far wide as to create a parallax distortion." 

Of course his reasoning is scientific and all about having the best spot in the room. His friends and loved ones know by now not to sit in his spot. The only other person worthy enough of this spot is Sheldon's "meemaw." The only woman who has his heart entirely.
