A man with two buckets of fish was leaving Boca Chica Beach, well known for its fishing and was stopped by a game warden.
The warden asked the man, "Do you have a license to catch those fish?"
The man replied to the warden, "No, sir. These are my pet fish."
"Pet fish?!" the warden replied.
"Yes, sir. Every night I take these fish down to this beach and let them swim around for about a half-hour, When I whistle, they all come back, jump back into my buckets, and I take 'em home. We do this every night."
"That's a bunch of hooey," said the warden. "Fish can't do that!"
"No, really! says the man. "Here, I'll show you." And he releases the fish in the ocean.
"Well, I've GOT to see this!" the game warden replied.
The man and the warden stood and waited. After several minutes, the game warden turned to the man and said, "Well, when are you going to call them back?".
"Call who back?" the man asked.
