hey I saw this show on National Geographic that had this tribe who for a "entering into manhood" ritual had their guys put on these specially made gloves with ants woven into them. They weren't just regular ants though, they were these really mean and biting ants (huge things) and they were pissed at being woven into these gloves. Well, they'd bite and bite and bite over and over again and these guys said it hurt so bad (some of them were crying) they lost any use of their hands for 12 to 24 hours. The wives, sisters of the group had to feed them and everything for like 12 hours because their hands were on fire. That is how one described it...that his hand was literally on fire.
I suggest the Ant Gloves.... Yeah, Ant Gloves strapped by barbed wire onto a bed of nails, face down while a randy elephant has it's way with him.
