You people are going to make it impossible for me to sleep tonight... im going to be sitting there thinking *gasp* I dont want there belts poking my eyes! (Ill have to wear an eye patch and kids will make fun of me and call me a pirate... or some weirdo with an eye patch)
Just to add to the belt scenario, when grappling my instructor ( a Judoka from an early age) goes north to south and makes sure the knot on the belt grinds into your face, he says it's a Judo trick. He also is fond of choking people with their own Gi jackets or t shirts, he however shrugs down into his Gi jacket so you can't get a choke on.
