Per wikipedia, "A Darwin Award is a tongue-in-cheek 'honor' named after evolutionary theorist Charles Darwin. Awards have been given for people who 'do a service to Humanity by removing themselves from the Gene pool', i.e., lose the ability to reproduce either by death or sterilization in a stupid fashion."
If you haven't been here before, I can't recommend a better way to spend a boring afternoon - while I admit the subject matter is decidedly morbid, the abject idiocy the victims display pretty much frees you from guilt by laughing at someone else's, often fatal, misfortune. In this case, schadenfreude is not only acceptable, it is entirely justified.
I find the ones involving botched burglaries, etc to be the funniest. A couple of doozies:
http://darwinawards.com/darwin/darwin2007-07.html - Burglary attempt, victim awakes, hits burglar in crotch with crutch - cue fun
http://darwinawards.com/darwin/darwin1998-03.html - car thief likes setting fire to cars when he's done using them - i'm sure you see where this one is going
http://www.darwinawards.com/darwin/darwin1999-38.html - Palestinian terrorists, Israel switching from Daylight Savings, time bombs - you can't be serious. Oh yes, I very much am.
