A foursome teed off on the long par-3. The green on this hole lay behind a large bunker, so any shot that made the green would disappear over the top ridge of bunker and you couldn't tell where your ball landed until you arrived on the green.  

After the last player hit his shot, the first golfer to hit charged off down the fairway, without waiting for the others. He disappeared over the bunker and seconds later came running back down the fairway yelling and screaming, "I got a hole-in-one! I don't believe it!"  

"You've got to be kidding," said the others. "You run ahead of us down the fairway and disappear behind that bunker, and now, all of a sudden, you claim you have a hole-in-one. How stupid do you think we three are?"  

"No, no. It's true. I swear it," he said crossing his heart. "Go look. I left it in the hole to prove it."
