Miraculous Golf Shot
Two men are standing on a golf course. The first one steps up, tees his first ball, and positions himself for a swing. The man lifts his club, swings smoothly down and smacks the ball into the air. It sails off in a nice, long arc, but as it comes down the two men can see that it's heading straight for the water trap.
Just then, a wind picks up, and a lily pad is blown directly into the ball's path. The ball lands on the lily pad, and after a few seconds a frog hops up onto the pad, grabs the ball in its mouth, jumps off the pad and swims for shore.
When the frog reaches dry land, it spits out the ball, and no sooner has it disappeared into the water than a squirrel comes running up to the ball, grabs it in its paws, and scampers off across the grass. But before it can reach the trees, a hawk swoops down out of nowhere, grabs the squirrel in its talons, and begins to climb back up into the sky. Panicked and struggling to get free, the squirrel releases the ball from its paws, and with the altitude and speed gained from the hawk, the ball sails down in a long, clean fall straight into the hole. Hole in one.
The second man turns to the first, and says "OK, God. Are you going to play golf or are you going to fuck around?"
