Larry David is a deeply personal writer. One wouldn't necessarily attribute a word like "personal" to the work of the social assassin, but it really is. It's not personal in the way that the grief-stricken Lana Wachowski wrote The Matrix Resurrections, but it's personal in Larry's remarkably observant and funny way. In fact, many of the best episodes of his acclaimed sitcoms, HBO's Curb Your Enthusiasm, and NBC's Seinfeld, were based on real-life experiences Larry had.

Of course, Seinfeld was famously created by both Larry David and Jerry Seinfeld, so the latter also had more than something to do with the best episodes. Not to mention the show had a team of writers who also brought their own life experiences into the show, such as the true origin of Festivus. But many of the best episodes of Seinfeld were based on Larry's crazy, frustrating, and downright hilarious life.

10 "The Pony Remark"

The second episode of the second season of Seinfeld is based around Jerry making a few comments about hating people who own ponies. Of course, the remark ends up insulting an elderly woman who passes shortly after. Jerry feels guilty and tries to apologize to her loved ones at the funeral. According to the episode commentary, Larry David almost made the same comments to an elderly woman who had a pony.

9 "The Cadillac"

After Larry David started seeing some financial success from Seinfeld, he purchased his father (who inspired the character of Morty Seinfeld) a Lexus. At the time, Larry's father was the head of the condo board and Larry knew that every one of his neighbors was commenting on his new car. While the story of Morty Seinfeld's neighbors accusing him of siphoning off some funds from the condo board was fictitious, the basis of the plotline was very much real.

8 "The Stake Out"

The plot for the second episode of the first season of Seinfeld was something that was inspired by Larry's own life, although he's not proud of it. In the episode, Jerry brings a date to a dinner but becomes more interested in someone else there. Because he can't flirt with her in front of his date, he decides to show up at her work and pretend to bump into her. This is something larry actually did.

7 "The Letter"

In "The Letter", Eliane is forced to take off an Orioles baseball hat while at a Yankees game. This precise thing happened to Larry David and his friend while sitting in Gene Autry's box. His friend was wearing a Yankee cap at an LA game and was forced to take it off. Afterward, Larry "had to put it in an episode".

6 "The Jacket"

In real-life, Larry David once dated the daughter of Richard Yates, the man who wrote "Revolutionary Road". And in real life his first meeting with him went spectacularly wrong. Although Larry did feel confident about the suede jacket he just bought. However, he had to turn it inside out to avoid the snow ruining it. Just like in the episode, the inside lining of the jacket was nowhere near as nice and it caused further embarrassment.

5 "The Soup Nazi"

While the iconic Soup Nazi wasn't based on Larry David's real-life experience, the whole "schmoopie" storyline was. It was actually Jerry who was doing a lot of baby talk with his then-girlfriend and it was driving Larry nuts so he had to put it in the episode.

4 "The Big Salad"

Larry David had the exact reaction that George had when his girlfriend presented Eliane with a big salad and took credit for purchasing it even though she hadn't. In reality, Larry had bought his Seinfeld editor a big salad but Jerry's assistant was the one who brought it to her and took credit for purchasing it.

3 "The Revenge"

In this season two episode, George viciously quits his job then immediately regrets it. Kramer then suggests that he go back to work the next day and pretend it never happened. This is precisely what the real-life Kramer (Larry's neighbor) told Larry after he quit the writing staff of Saturday Night Live. The day after he told off his executive producer and quit, Larry returned to the iconic NC sketch show and pretended he never told anyone to "go f*** themselves". It worked.

2 "The Pitch" And "The Ticket"

The entire plotline of Jerry and George creating a show for NBC was based on Jerry and Larry creating a show for NBC. Many of the details in the multi-episode plotline, specifically in "The Pitch" and "The Ticket" were directly ripped from real-life meetings with network executives. This includes their reaction to the whole "show about nothing pitch".

1 "The Contest"

While creating the most controversial episode in Seinfeld's history, Larry David drew from his own experience. He too was involved in a contest of the same nature with his friends. Even though NBC was totally opposed to the idea, Larry knew that it had to be put in his show. Larry got his way and the rest is history.
