Laughter is the most educational medicine.

Reason Magazine - Who's Afraid of Mahmoud Ahmadinejad?:

"If you saw C-Span's abbreviated coverage of the event, you may have noticed the many yarmulkes adorning heads in the audience. I doubt the people who wore them admire Ahmadinejad any more than Silver did. But they apparently understand that the solution to bad speech is more speech, and that even bad speech can be valuable. In response to one query, about the mistreatment of homosexuals in Iran, Ahmadinejad claimed that there simply are no gays in his country: 'In Iran we do not have this phenomenon. I don't know who has told you that we have it.' Anyone listening to that lie learned a lot about Iranian society. Ahmadinejad himself may have learned a thing or two from the laughter that swept the room after his answer."
