A hack golfer spends a day at a plush country club, playing golf & enjoying the luxury of a complimentary caddy. Being a hack golfer, he plays poorly all day. Round about the 18th hole, he spots a lake off to the left of the fairway. He looks at the caddy and says, "I've played so poorly all day, I think I'm going to go drown myself in that lake."
