Ice Fishing

A blonde decides to go ice fishing one day. She takes her stool and her fishing pole onto the ice, and cuts a big hole. Then a voice says:
"THERE ARE NO FISH UNDER THE ICE"
Perplexed, the blond moves her stool 100 feet, sits down again and goes to work cutting another hole. Again, the voice said:
"THERE ARE NO FISH UNDER THE ICE"
Clearly flustered, she moves the stool to one last spot, sits down, and picks up her auger. Again, the voice boomed:
"FOR THE LAST TIME, THERE ARE NO FISH UNDER THE ICE"
Finally, she can't take it. She cries out, "God, is that you?"
"NO, I'M THE OWNER OF THIS HOCKEY RINK"
