"God of the Ice Rink" joke

A guy gets up really early in the morning to go ice fishing.

He goes out onto the ice with his tent, his pick and his fishing rod, and starts to pick at the ice.

Then he hears a big booming voice: "THERE'S NO FISH UNDER THE ICE"

The guy looks around and then starts to pick at the ice again.

Then he hears the voice again: "THERE'S NO FISH UNDER THE ICE"

Now the guy is getting a little edgy.

He looks up, "God, is that you?"

There is no answer, so he starts picking again.

"THERE'S NO FISH UNDER THE ICE!!"

Then the guy yells "God! is that you?"

"NO, IT'S THE MANAGER OF THE ICE RINK!!"
