Quote from Andy in The Master Plan
Andy: Let me ask you a quick question. What's the youngest a girl can be that if we go out, I'm not a total scumbag? Tom: You know the old rule. Half your age plus seven. Andy: Half my age plus seven. Oh, okay. Well, I'm 29, so half of 29. Add seven. That's only... Twenty is... Tom: Twenty-one... Andy: Twenty-years-old. Tom: Twenty-one... and a half. Andy: Twenty-one-years old and a half. Tom: Yeah. Andy: Yep. We got the same thing with the equation on that one.
