A camper was stopped by a DNR Game Warden in Michigan as he was returning to his campsite with a bucket full of still-alive fish. "Do you have a license to catch those fish " the game warden asked. "No sir, these are my pet fish," the man replied. "Pet fish?" the warden asked. "Yes, sir. Every night I take these fish down to the lake where I'm camped and let them swim around for a while. When they hear my whistle, they jump right back into the bucket and I take them back to the camp." "That's a bunch of baloney," the game warden said as he reached for his pad of citations. The man looked at the game warden for a moment and then said, "If you don't believe me, then follow me back to the lake to see how it works." Still suspicious, but curious, the game warden agreed. And so they walked to the lake. There, the man poured the fish into the lake, where they disappeared into the water. "Okay," said the game warden. "Call them back." "Call who back?" "The fish," replied the warden. "What fish?" asked the man.
