A man was stopped by the fish and game warden. He had with him two buckets of fish. The fish and game warden asked the man, "Do you have a license to catch all those fish?"

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

"Pet fish?" the warden replied.

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

"That's a bunch of hogwash! Fish can't do that!" was the outburst from the Warden.

The man looked at the game warden for a moment, and then said, "Here, I'll show you. It really works." The man poured the two buckets of fish into 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!" the warden said.

"What fish?" the man asked.
