Big Bang Theory Quote
Amy: Hey, did you guys know that Sheldon a best friend growing up named Tam?
Leonard: Was that the imaginary talking koala?
Amy: No. He's a real person who apparently betrayed him.
Leonard: Yeah, so did the koala.
Amy: I tried to ask him about it, and he invoked section three, article five of the marriage contract: "beeswax, none of your". I can't pry. I mean, I have to respect his wishes.
Howard: Wow. I wonder what that guy could've done to make Sheldon not talk to him for twenty years.
Leonard: I wonder if it'd work a second time.
