(There is a knock on the door. I open and there’s a guy, obviously uneasy, holding a ADT security sign in his hand.)

Salesman: “Good evening. How would you like to have one of these on your lawn?”

(It really looks like this is his first attempts at selling security systems. He’s really nervous.)

Me: “Yes, sure. Just put it right in front of the living room window, please.”

Salesman: *taken aback* “Err… it’s that… you have to buy a security system to get it.”

Me: “Ah. No thank you, then. Goodbye.”
