What happens to a man's penis in cold water. Often a result of cold showers, swimming pools, or the ocean. Very embarrassing.
Man, that pool could make a porn star look like a 9 year old.

Damn my girlfriend dumped me when she saw me get out of the shower -- apparently she doesn't understand that shrinkage really CAN make a penis 1 inch long.
