Phone Conversation 2

Caller: Is this George's Plumbing?
Me: No, it isn't, but that does seem to be the question of the day.
Caller: What?
Me: You have the wrong number.
Caller: Oh, sorry. Do you have the right number?
Me: I have the right number for me.
Caller: What?
Me: No, I don't have the number for George's Plumbing. However, I'm assuming it's similar to this one, so maybe if you just start calling, but change one or two numbers, eventually you'll get the right place.
Caller: What?
Me: Or, you could look it up again in the phone book.
Caller: Where do you think I got this number?
Me: Off a restroom wall?
Caller: What?
Me: Good-bye.
Caller: Good-bye.
