Bialik, Mayim
From The Big Bang Theory Wiki
Actress who "played TV's Blossom". When the guys needed to find a fourth person for their Physics Bowl team, Raj suggested that they enlist Bialik:
- "You know who is apparently very smart is the girl who played TV's Blossom. She got a PhD. in neuroscience or something." (0113)
Bailik actually does make an appearance on the show; she plays Amy Farrah Fowler.
