A man was stopped by a game-warden in East Texas recently with two buckets
of fish leaving a lake well known for its fishing.  The game warden asked
the man, "Do you have a license to catch those fish?"

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

"Pet fish?!"  the warden asked.  

"Yes, sir.  Every night I take these here 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 em home."

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

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

"O.K.  I've GOT to see this!."  The game warden was curious now.
The man poured the fish in to the lake and stood and waited.  After several
minutes, the game warden turned to the man and said, "Well ?"

"Well, What?" the man responded.

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

"Call who back?" The man asked.

"The fish." replied the warden.

"What fish?"  The man asked.
