A fisherman is loading his boat when the Game Warden walks up. The warden ask if caught anything and the guy answers back, " I wasn't fishing, I was letting my pet fish swim." The warden opens a large tank on the boat and sure enough it was full of fish. The fisherman explained that he has a small pond where he keeps his pet fish and ever so often he lets them swim in the lake. After the fish were swimming for a while he would lower the tank into the water, bang on the side and his fish would return to the tank. The warden was in amazement and ask the fisherman if he could observe such a feat. The fisherman lowered the tank and all the fish swam off. After a short time the warden ask the guy to call his fish back and the man answers, "What fish you talkin about?"
