Stupid Questions

And another one on IRC. There's the saying that there's no such thing as a stupid question. That's wrong.
My list of stupid questions, ordered by stupidity:
-May I ask a question? (You just did...)
-Somebody used XYZ? (Of course, if somebody created XYZ, then obviously somebody used XYZ...)
-Anybody around who could help me with XYZ? (Ask and you shall see...)
