6. The best reply to some telemarketers was done by a friend of mine

Mind you, this was back in the mid 90s when phone companies were scrambling to offer internet service... It essentially went like this (jumping into the middle of the conversation after the initial sales pitch from the telemarketer, who was female)

Friend: I don't know... I'm pretty happy with my current phone service. They offer me X cents per minute on the weekends. Do you offer that?
Telemarketer: Yes, sir, we do!
Friend: Oh, really? Well, the other nice thing is that they bundle my phone and internet together into one bill, and I wouldn't want to lose that. Can you do that?
Telemarketer: Yes, sir, we can!

*he rapidly goes through several other things that he knows the phone company offers to condition her to keep saying yes.

Friend: Well, there's also the ten cents a minute phonesex. Do you have that as well?
Telemarketer: Yes si... I'm sorry, what did you say?
Friend: The ten cents a minute phonesex. Do you have that as well?
Telemarketer: *silence*
Friend: So... what are you wearing?
Telemarketer: *hangs up*
