The Snail

There was this guy sitting in his living room watching the tv and he heard a knock on the door. he got up off the couch to answer it. he opened the door and noticed a snail sitting there on his doormat. agitated as he was for being interrupted, he picked the snail up and threw it into the front lawn. a year later, he was watching tv in his living room as he usually does and he heard a knock at his door. he opened the door and there was the snail and the snail said "what the heck did you do that for?"
