A young game warden sees a man on the river with a bucket of fish and a pole. Asks for his fishing license. Man says he wasn't fishing. He says, “These are my pet fish I bring them to the river twice a week for exercise. I dump them in, wait 5 minutes and when I whistle, they jump back in the bucket.”
Game Warden says no way. Guy says, “Let me prove it to you and if I'm wrong you can give me the ticket.” Warden says ok.
The guy dumps out the fish and sits on the bucket. After 5 minutes the warden says "Well?"
Well what?"
"Aren't you going to call your fish?"
"What fish?"
