A hack golfer spends a day at a plush country club, playing golf, enjoying the luxury of a complimentary caddie. 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 caddie and says, ‘I’ve played so poorly all day; I think I’m going to go drown myself in that lake.’
The caddie looks back at him and says, ‘I don’t think you could keep your head down that long.’
