I heard a funny thing about orangutans once. It goes something like this -  if you leave a screwdriver in a gorilla's cage, he'll try to eat it, if you leave one in a chimp's cage, he'll bang on things with it, if you leave it in an orangutan's cage, he'll hide it until everyone's gone, then he'll unscrew the hinges of his door and escape!

Don't argue with an idiot; people watching may not be able to tell the difference
