Given the amount of very stupid people in today's world, I thought I would dedicate a thread to them.
Just tell us the stupidest things you have ever seen...
For starters, here's a good website for this: http://www.darwinawards.com
And here's mine:
A student who was very interested in a teacher's demonstration of the effect of sodium in water decided to do some testing of his own. He extracted some sodium from the tank of oil it was stored in (to prevent a reaction) and wrapped it in paper towel, then put it in his pocket. Eventually, his sweat soaked through, and POOF! he experienced the demonstration firsthand. He experienced severe burns to his private parts as well as his legs.
