The widely accepted rule of mentality that witty retorts, good comebacks, and the right thing to say will always come ten minutes or more after you need it.
Bob: At least somebody will get in bed with *me*.

Joe: Uh...erm.... STUPIDFACE!

*ten minutes later*

Joe: "At least my sister doesn't whore it up with me". Genius. Why didn't I get this when I needed it?

Carl: Rule 41.
