A guy was stopped by a game-warden in northern Pennsylvania recently with two buckets of fish leaving a lake well known for its fishing.

The game warden asked the guy, "Do you have a license to catch those fish?"

The guy replied to the game warden, "No, sir. These are my pet fish."

"Pet fish?!" the warden replied.

"Yes, sir. Every night I take these fish down to the lake and let them swim around for a while. I whistle and they jump back into their buckets, and I take them home."

"That's a bunch of hooey! Fish can't do that!"

The guy looked at the game warden for a moment, and then said, "Here, I'll show you. It really works."

The game warden was curious now. "O.K. I've GOT to see this!"

The guy poured the fish in to the water and stood by and waited. After several minutes, the game warden turned to the guy and said, "Well?"

"Well, What?" the guy responded.

"When are you going to call them back?" The game warden prompted.

"Call who back?" the guy asked.

"The FISH."

"What fish?" the guy asked.
