Craziest place you've ever been able to fall asleep?

I got a haircut yesterday and I seriously started to drift off when she was washing my hair and then again when she was cutting my hair. It's not that much of a surprise considering both of those things are incredibly soothing and relaxing. I also don't have much of a problem falling asleep sitting up and/or in places I probably shouldn't be falling asleep.

I think the craziest place I've been able to actually fall asleep is on an airport bench, you know the ones with those hard armrests that do not move. Still not entirely sure how I contorted my body to sleep there, but I did it. (Oddly enough, I have a really hard time sleeping on actual planes. Go figure.)

So, where's the wildest place you've been able to get some rest?
