I've got 2.
5th hole is a 180 yd par 3. Just short and left of the green is a small apple tree. A member of my foursome hits his ball into that tree. He's under there preparing to chip, and asks us to watch for his ball, his view is blocked. He hits the chip, ball flies leaves and branches, lands on the green, and goes in the hole!!! We're all hooting and hollering at what a great shot it is, and he says what do you mean, my ball is still in the tree. We go and look at the cup, and its an apple in the hole.
the second was staged. A friend of mine is a bit of a trickster, and he takes two balls, tees one up, and balances the second on top of that. He then takes a swing at the bottom ball, which he hits down the middle, and the top ball pops up in the air about 6 feet. He catched the top ball and puts it in his pocket. Pretty cool to see it
