Just for laughs!
A deep-sea diver is twenty feet below sea level when he sees another guy with no scuba gear. He goes down another thirty feet, and the guy with no equipment stays with him. He takes out a waterproof chalkboard and writes, "How the hell can you stay down this deep without equipment?" The guy takes the chalkboard and writes, "You a**hole, I'm drowning."
