The man takes a look through the scope, and starts laughing.
"What's so funny?" asks the clerk.
"I see a naked man and a naked woman running around in the house," the man replies.
The clerk grabs the scope from the man, and looks at his house. Then he hands two bullets to the man and says, "Here are two bullets, I will give you this expensive scope for free if you take these two bullets, shoot my wife's head off and shoot the guy's penis off."
The man takes another look through the scope and says, "You know what? I think I can do that with one shot!"
