Dividing a football field into one foot by one foot squares throughout the entire field. Then selling raffle tickets to each of the thousands of squares. Next, renting a cow (moo) and having everyone feed the cow until it poo's. If the cow poo's in your square you win.
Do you want to buy a moo poo raffle ticket?
No, I don't want to spend my Saturday watching a cow shit on the ground.
