The Big Bang Theory: 15 Insane Details You Definitely Missed
8. Blossom And Joey Was A Couples Costume Idea For Sheldon And Amy
There have been several references to the real-life Mayim Bialik's time playing Blossom Russo on the eponymous nineties show; perhaps the most memorable occurrence came in the very first season as Raj suggested "the girl who played TV's Blossom" as the fourth member of his, Leonard, and Howard's Physics Bowl group.
Another secret reference slid its way into the show's later seasons, though, as in season six's "The Holographic Excitation", Sheldon and Amy create a Venn diagram to decide on their Halloween couples costume for the party Stuart is hosting at the comic book store. Many typical Big Bang Theory references are made here, particularly on Sheldon's side of the board as he lists R2-D2 and C-3PO, Batman and Robin, and the Doctor and a Dalek as possible costumes.
On Amy's side, however, are some more traditional couples costume ideas. Cinderella and Prince Charming, Romeo and Juliet, Jack and Rose, and Blossom and Joey. That last one is, of course, referencing Mayim Bialik's time on the iconic show, with Joey - played by Joey Lawrence - being one of her fictitious brothers.
