When Sheldon and Leonard get into an argument, Leonard goes to Penny's. She quizzes him on why he ever moved in with the guy. What follows explains some of the best stuff I've ever seen. We get to know how the two got together. We find out how Howard and Raj came into the picture. We find out why the elevator hasn't worked for seven years. We get to know the crazy roommate agreement. It's hilarious from beginning to end.
