The Diver

[Rondy]

One day, a diver was enjoying the aquatic world 20 feet below sea
level. He noticed a guy at the same depth he was, with no scuba gear
on whatsoever.
The diver went below another 10 feet, but the guy joined him a minute
later. The diver went below 15 more feet, and a minute later, the same
guy joined him.

This confused the diver, so he took out a waterproof pad and pencil,
and wrote, "Amazing! How are you able to stay this deep down without
equipment?"

The guy took the pencil and pad, erased what the diver had written,
and wrote, "I'm drowning, you moron!"
