(This happened to a friend of mine who owns a gun shop.)

Friend: “Hello, this is–”

Caller: *twelve year old sounding voice* “Your mom!”

Friend: “What?”

Caller: “What your mom said.”

Friend: “A prank caller are we?”

Caller: *mocking tone* “A prank caller are we?”

Friend: “Do your parents know what you’re doing? Because I have caller ID and I can call them back later.”

Caller: “My parents are out of town… duuuhhh!”

Friend: “You must have absolutely no idea what kind of store you just called, then.”

Caller: “A GAY store?”

(My friend puts the phone down and opens the locker behind the counter and retrieves a shotgun. He holds it next to the phone and pumps the action.)

Friend: “Can you guess now?”

Caller: “…”

Friend: “You know, your caller ID gave me a first and last name. All I need to do is open a phone book and I can find your address.”

Caller: *click*
