On CBS's The Big Bang Theory, we've met Sheldon's mother. Emmy-winner Laurie Metcalf appeared in season one as a super-religious Texas mama who knows better than anyone how to get to Dr. Sheldon Cooper. Now, Leonard's mother is going to be introduced, and she's equally as accomplished as Ms. Metcalf.

Tony, Emmy and SAG award winning actress Christine Baranski will be Leonard's mom, Dr. Beverly Hofstadter. That's right, she's a brainiac.

Her specialty is research on the human brain, and according to Bill Prady, Big Bang's executive producer, "There's the possibility that Leonard is the least successful in his family, that his parents always pushed him toward academic success." Sounds like a funny set up to me.
