Kim DuToit calls this guy the moron of the year, and it's hard to argue.
Some commenters offered alternate candidates, such as the guys who let fireworks explode in their mouths. The guy with the M-80 lived, the one with the M-100 did not. The pictures are nasty.
I don't know if the commenter's story about the .22 bullet used as a fuse is for real or not, but who cares? - it deserves to be true.
