Durban II: Mad Ahmad is coming - what should I ask?

According to the perspicacious Anne Bayevsky, who (along with Claudia Rosett) covers the UN as well as anyone, Mahmoud Ahmadinejad will be attending the Durban Review Conference in Geneva April 20-24. Since I’m going to be there, covering the event for PJTV, what should I ask him (if perchance I get the opportunity)? Whether he’d like to amend or extend his statement that there are no homosexuals in Iran? Or how about whether he is planning another Holocaust denial art show? I solicit other questions. But remember: be respectful. This is a UN Human Rights conference.
