Comedy Joke: Six feet below

[yetadem]

A pool diver was six feet below pool level when he saw another guy with no swimming float.

He goes down another twelve feet, and the guy with no equipment stays with him. He took out a waterproof chalkboard and wrote, "How can you stay down this deep without equipment?"

The guy took the chalkboard and wrote, "You fool, I'm drowning, help!"
