This is long but worth the read------ My buddy is a roofer, he was doing a big job in the summer, he was dumb enough to wear sweet pants that day. at lunch break all the guys were sitting on an old cinder block wall that was kinda rickety . the blocks were kinda separated and moved alot. he sat down dead middle of 2 blocks, his balls hanging low went into the gap between then, as he put the weight of his body on the blocks, they squeezed together and pinched them.. he cursed and jumped up, said it was worst pain in life. everyone laughed at him. I guess he didnt ruin them, he has many kids now but i cringe at the thought lol
