I just read about this over at the L.A. Times website. Seems like ol' Osama couldn't wait for his 72 virgins. I imagine the exchange going something like this:
Guard: Osama, what are you doing in there? Why is this door locked?
ObL: [muffled through the door] Ugh, I am...ugh...just...cleaning! Yes, cleaning.
I tried to think of a good porn name for bin Laden, but I couldn't think of anything postworthy.
