Most people don't understand most things, but they still try to use them regardless. Sometimes that's a good thing. Sometimes it isn't.

I love the 'say 'no' while doing the thing asked of you' joke. When I'm pulling it, it's only funny if I do the thing. I know that, so I make sure to telegraph my motions, to make sure the other person got the joke. After all, if they don't, it's not funny.
