A game warden sneaks up on a fellow fishing in a pond. Game warden, pointing to a bucket of fish, says:
Are those your fish?
Yes sir.
Can I see your fishing license?
No sir.
Well, I'll need those fish for evidence.
But sir, I don't need a licesense for those fish.
What do you mean?, said the warden?
Those are my pet fish. I'm just bringing them for a swim.
You mean, you can put them into the pond, and they will come back?
Yes sir, I just whistle for them and they come right back and jump into my bucket.
Now you're just BS'ing me.
Well sir, it really works.
OK, I've got to see this! says the game warden.
Our hero dumps the fish into the pond, picks up his rod, and starts walking to his truck.
Game warden says HEY! Aren't you going to whistle for them?
Whistle for what?
Your pet fish!
What fish?
