Until he was a bloomin' nine year old, my cousin believed that his penis would fall off one day. So, thinking he was hilarious, my uncle, during a family party, dropped a chicken sausage (the cocktail type) on the pretty clean floor, and went, "Oh my God! (Inserts cousin's name), that's your dick, ain't it?" My cousin instantly burst out crying, as my uncle casually picked up the sausage and ate it.
He's 12 now, and I think he's still afraid of losing an important part of the male anatomy, since he takes only a minute (literally) to enter the toilet, pee, wash his hands and exit.
