Old golf joke: Using the new ball

A keen but unskilled golfer plays the same course every week, and has particular trouble with the water trap on the 14th hole, losing a ball in it every time he plays that hole. One round he decides that this process is too expensive and decides to use an old cut-up ball instead of a good ball.

He opens his bag and gets the old ball, tees it up and addresses it. Just as he commences his back-swing a mighty voice comes from on high:

“USE THE NEW BALL…”

Figuring any advice from such a source should be worth following he picks up the old ball and tees up the new one again. He starts his back-swing but once again is interrupted by a voice from the sky:

“TAKE A PRACTICE SWING…”

The man steps away from the ball and rehearses his swing. Just as he steps forward to readdress the ball, the voice speaks again:

“USE THE OLD BALL.”
