Ultimate Dairy Golf

A game played in the dairy backroom at ShopRite.
It involves a tape ball, a large hook, and a garbage can.
The object of the game is to flip the tape ball into the garbage can with the hook.
It will be a future winter Olympic sport.
Currently Jerry is the UDG champion because no one can defeat him.

WOW!! Did you see that crazy shot Jerry just made? He is a UDG champion!
