I did this once... on the Wii, but the other day German golfer Martin Kaymer really did make this amazing shot during a practice round for the Masters in Augusta, Georgia.

It's sort of a tradition to try the shot on the par 3 16th hole at Augusta, and Martin did skip his ball, and got a hole in one.  A bystander got some cell phone video and posted it to YouTube... ( The second shot is Martin's.)
