Twenty feet below sea level, a diver notices another guy at the same depth with no scuba gear.

The diver goes down another 10 feet, and the guy joins him a minute later. The diver goes below 15 more feet, and a minute later, the same guy joins him.

The diver takes out a waterproof pad and pencil and writes, “How are you able to stay this deep without equipment?”

The guy takes the pencil and pad and writes, “I’m drowning, you moron!”
