I know this sounds funny, but I'm serious. I think it might just work. That's why I didn't put it in the humor category.
Some Hollywood actors (might have to be lesser known ones), make-up artists and special effects people could stage a phony ghostly appearance of some dead suicide bombers to tell their live bretheren that there are no virgins in the afterlife.
Maybe they couldn't or shouldn't do it live. Maybe it should be a hologram projected on a cloud or something.
