Stick Figure in Peril
Part of a great Flickr group: stick figures in peril. This one is about to be clobbered by a giant beer bottle.
A stick figure getting crushed by a bobcat is great, too. Or the one instructing you to please not run over children with a lawnmower. Great stuff.
My favourite so far, though, is the don't drive your wheelchair downhill at a crocodile one. Or fire kills children!
