I know he's not even finished speaking and the little nutter could come up with something better, but I don't see how!
Someone in the audience at Columbia asked about Iran executing homosexuals "......your government has imposed draconian punishment, including execution of Iranian citizens who are homosexuals. Why are you doing those things?".
Iranian president Mahmoud Ahmadinejad answers "In Iran we don't have homosexuals like in your country. We don't have that in our country. In Iran we do not have this phenomenon. I don't know who has told you that we have this."
Lot's of laughter followed that one!
***UPDATE***** Breitbart has video on this.
