Body cavity Puns

My dad is a all around generally funny guy but for me one of the funniest things he said to me was once while he was cleaning a bunch of fish he had caught. I was watching with wonderment how quickly he was going through the catfish he had caught that day. He was very seriously removing the head and skining them and gutting the fish. He had one particular fish's head on the cutting board seperated from the body and he had the completely gutted body of the fish in one hand and the garden hose in the other. He was running water on the inside cavity of the fish and the tail was twitching back and forth, he noticed my amusement at this and said to me with a sly grin,"they don't like that cold water on their belly." This may be one of those you had to be there moments but I thought it was hilarious at the time.
