After Leonard and Sheldon have a heated argument about what Sheldon sees as Leonard making a major breach in the roommate agreement, Leonard takes refuge at Penny's apartment. Despite the seriousness of the argument, Leonard assures Penny that Sheldon was much more difficult to live with when Leonard first moved in. Leonard recounts to her his first meeting with Sheldon seven years earlier when Leonard answered Sheldon's advertisement looking for a new roommate. He also recounts Howard and Raj's first encounters with Sheldon, what happened to the now broken elevator which was working when Leonard first moved in, and why Leonard decided to stay despite Sheldon being such a difficult and unusual roommate.

Ever since the start of the show, the big question on everyone's mind is "what happened to the elevator?" Finally, in a flashback episode to reveal how everyone met -which are always fun- it is shown why they must walk three flights of stairs.
From start to finish, this episode is a laugh riot and makes your stomach hurt from all the laughing. It's creative and interesting to learn how Leonard comes to live with the freak Sheldon. It's interesting how Sheldon is worse before Leonard arrives and it's great to see that Howard and Raj have always been lovable and quirky.
It would have been interesting to watch the show starting back in 2002 and venturing all the way until Penny moved in and such, but it's a great show and seems to improve with each episode.
