Unknown caller from Florida...called it back and got a message saying "you've reached a non-working number." Really? Then how did I just get a call from them?
I called 4-1-1 and was told there was no such number.
I like your ideas although would avoid joking about a 'car bomb' with all the post 9-11 laws and surveillance. It would be amusing to ask them what kind of underwear they have on or if they 'touch themselves' while on the phone with patrons. Who knows, this may net you more calls, not fewer...
