Only thing worse than fireants would be bullet ants... Though I heard a story of a 6 year old boy that stepped in a fire ant nest that was so developed that he fell 2 and a half feet in the ground and by the time he realized it, they were up to his torso. Unfortunatly the toxins took over in a matter of minutes and he died on spot.
I'm suprised no one has mentioned having all of your teeth pulled without being drugged up. With a corkscrew... by a guy with parkinsons.... on a tugboat... in the middle of a huge storm.... and the ship happened to be sinking... with sharks in the water... hungry sharks.. that only craved male genetalia.... okay im gonna stop there... If you people didnt think I was insane before... this one did it for sure.
You could also watch Numa Numa Dance for hours on end. Eventually you'd find a way to kill yourself without any means of doing so.
