Joke | There are no fish

A guy goes ice fishing for the very first time.
All of a sudden, he hears a voice. “There are no fish under the ice!”
He ignores it and moves to another area, cuts a hole, and tosses his line in.
Again, he hears the booming voice: “There are no fish under the ice!”
He nervously looks up and asks, “Lord? Is that you?”
“No, this is the rink manager!”
