After a day of fishing in the ocean, a fisherman is leaving the pier carrying two lobsters in a bucket. The game warden appears, asking for his fishing license.
The fisherman says, “But, I did not catch these lobsters, Officer. They are my pets. Every day, I come down to the water and whistle, and these lobsters jump out. I take them for a walk, only to return them at the end of the day.”
The warden doesn't believe a word of it and tells the man so.
"All right," says the fisherman. “If you don’t believe me, then watch.”
He throws the lobsters back into the water and waits.
The warden says, “Now, whistle to your lobsters and show me how they come out of the water.”
The fisherman turns to the warden and says, “What lobsters?”
