One of my favorite ribs, when I was in wrestling school we only had one female student. She would always shower and use the locker room first, and when she was done, then we would all use it.
One day we decided it would be funny if we sent someone in and acted like they were going to rape her in the shower. So my buddy Nick gets totally naked, walks in and starts grabbing her and getting real physical and she starts screaming. This went on for about 3-4 minutes and Nick came walking out with an erection and we all popped. She came ouf of the shower crying and ran out and we were all on the floor rolling laughing. The next day, one of my friends uncles who is a cop showed up and started asking questions, and we explained the rib to him. He cracked up laughing and shook his head and said "You guys are crazy" and left. Those were the good ole days.
