A man goes into a sex shop and asks for a sex doll. "Would that be a male doll or a female doll?" asks the helpful assistant. "A female doll, of course." "Certainly sir. Would that be a black doll or a white doll?" "Mmm...a black doll, I think" "Certainly sir. And would that be a christian doll or a muslim doll?" "Eh? I didn't know that mattered - what's the difference?" "Well sir, the muslim doll blows itself up!"
