A hack golfer

A hack golfer spends a day at a plush country club, playing golf and 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.”
The caddy looks back at him and says, “I don’t think you could keep your head
down that long.”
