Asking for a Friend

Alright, listen up, buttercup. This ain't rocket science. The joke here is that the person is ALREADY asking the question "for a friend." Asking how to ask "for a friend" is the joke. It's like saying, "I'm not dumb, but my friend is, and I need to know for my friend who is dumb, not me, because I'm smart." I know you're too dumb to understand, but you need to know this, you are dumber than a bag of hair.
