The Big Bang Theory, Season 2

Leonard:
[attempting to get back at Howard and Raj, who were asking Beverly to talk about Leonard's more successful siblings] Howard lives with his mother, and Raj can't speak to women unless he's drunk. Go!

Beverly:
Oh, that's fascinating. Selective mutism is quite rare. On the other hand, an adult Jewish male living with his mother is so common, it borders on sociological cliché.

Howard:
It's just temporary. I pay rent.

Leonard:
He lives in the same room where his bassinet was.

Beverly:
You know, both selective mutism and an inability to separate from one's mother can stem from a pathological fear of women. It might explain why the two of you have created an ersatz homosexual marriage to satisfy your need for intimacy.

Howard:
Say what?
