What a fish

Prompt for 6/7
Write a story that includes the words: painting, fish, bag

I was at the lake and saw a man catch a surprisingly big fish. he thought he had a snag. He pulled in the snag and it was actually a 72.1 pound blue channel catfish! It was as big as the fisherman himself. He had been fishing in a tournament, which he of course won with that big cat. I always wondered though. Why are they called "catfish"? They look nothing like my cat! The catfish will make a nice trophy to replace the painting on his wall. Now if he would just bag me one!
