Bet on a bullet
A man walks into a gun shop.
“I want to buy a new scope and bullets for my rifle”
“sure” said the owner handing over a scope “if you look out the window, this scope is so powerful you can see into my house”
The man looks, then turns to the shopkeeper and says “sorry mate there is a man in there and a woman who i can only assume is your wife?”
“cheating, bitch!” the shopkeeper said, putting two bullets on the counter he said “Shoot that guys prick off and you can have the scope for free, shoot that bitches’ head off and I’ll give you free bullets for the rest of your life”
The guy looks through the scope again and says “what do I get if I only use one shot?”
