Stories of friendship, whimsy, and musical episodes served with one of J.D.'s very favorite "Appletini" drinks, are just a few reasons why Scrubs was so beloved among TV devotees.

Of course, life isn't entirely comprised of songs about friendship, and nuggets of life wisdom; there were lots of behind-the-scenes happenings on the set which almost shatters the illusion of Turk and J.D.'s perfect friendship.
