Dogbert is right, there are stupid questions, and this was comic was a clever way to show it. Dogbert's rambling in the second panel led Dilbert to ask a question already answered in the first panel. His question should have been, "What were you going to ask me?" Another stupid question, IMO, is this, "Can I ask you a question?" Obviously the answer to that question is yes.
So it looks like Stormthehouse has only one talent: posting comments that reiterate what someone before him said, only less intelligently and more verbosely.
