Its like that Seinfeld one:

Telemarketer: Good Evening sir, could I interest you in blah blah blah...

Jerry: Oh, you kind of caught me at a bad time, do you think we could talk about this some other time? Why don't you give me your home phone number and I'll give you a call back tonight?

Telemarketer: Uh... no, I don't want you calling my home...

Jerry: Now you know how I feel..


(or something along those lines)
