Joe decides to go ice fishing, so he gathers his gear and goes walking around until he finds a big patch of ice. He heads into the center of the ice and begins to saw a hole. Suddenly, a loud, booming voice startles him.
“You will find no fish under that ice!”

Joe looks around, but sees no one. He starts sawing again. Once more, the voice speaks.

“As I said before, there are no fish under the ice!”

Joe looks around, high and low, but can’t see a single soul. He picks up the saw and tries one more time to finish. Before he can even start cutting, the huge voice interrupts.

“I have warned you three times now! There are no fish!”

Joe is now flustered and somewhat scared, so he asks the voice, “How do you know there are no fish? Are you God?”

“No,” the voice replies. “I am the manager of this hockey rink.”
