Trivia: When Leonard, Howard and Raj are contemplating who to have as the fourth member of their Physics Bowl team, Raj says, "You know who's apparently very smart is the girl who played TV's 'Blossom'. She got a Ph.d in Neuroscience or something." The girl he's referring to is actress Mayim Bialik, who plays Amy Farrah Fowler in later episodes of The Big Bang Theory.

The Excelsior Acquisition - S3-E16

Trivia: Raj's question about why so many of Stan Lee's characters' first and last names begin with the same initial (Peter Parker, Reed Richards, Bruce Banner, etc.) has been answered by Lee in interviews before: He has a bad memory for names, so if he can remember one of their names, he knows the other starts with the same letter.

Trivia: When Amy sings "Soft Kitty" in German she more or less translates it literally. The German dubbed version of the show uses completely different lyrics for its rendition instead of just translating the original version.

Leonard is always on the sofa left to Sheldon, Penny is almost always on the sofa across Sheldon, Howard is always next to Sheldon on the couch (except in situations when Amy or Bernadette sit between him and Sheldon), and Raj is always on the left side of the couch (viewers' left), or on the floor.
