Gun Shop Incident

gunA man is at a gun shop looking to buy a new scope. The scope is on a rifle and he is looking through it out the window seeing if he likes it. Suddenly the man exclaims, “Oh sweet! Check it out! A naked chick and guy.”
The shop owner picks up a nearby set of binoculars to see and says, “Fuck! That’s my wife and another man.”
The shop owner tells the guy, “If you take these two bullets and shoot my wife in the head and that guy’s dick off, I will give you the scope for free.”
The man says “OK, but I think I’ll only need one bullet.”
