A challenge!

Here’s a request from gnosos:

“Dr” Hovind is giving a speech on my campus tomorrow night in a 450 seat auditorium. Usually, questioners only get 15 seconds at the mic at these kinds of things, and I’m trying to think of a question that approaches one of his many glaring errors in thought in a novel way. Do you (or your readers) have any ideas about what you (or they) would say to Kent Hovind given 15 seconds?

I’m cynical: I think the rapid-fire limitation is intended to prevent deep, thoughtful questions or any kind of considered rebuttal, and I also think he’ll just reply to anything with more empty-headed, rote creationist jingo, so I think it’s all an exercise in futility. But maybe someone here can come up with a simple stumper of a question.
