I got owned by a telemarketer one time though. It was morning and I was sleeping still, and answered the phone. They asked me to take down a number and I said "Oh, okay hold on" pretended to get a pencil and paper "Ok give me the number" I said.
The telemarketer then proceeded to give me some silly 1800 number, and I said "Ok thanks" and before I could make my getaway to my sleepy slumber of goodness, they said "Read it back to me.."
GASP! Read it back? I didnt even write it down! "Uhhhh..." I said, suddenly waking up in full, only to admit that "I didnt write it..down.. I was..sleeping.."
He laughed, and made me actually go get the pencil and paper, and write the fucking number down. Then, he didnt even ask me to read it back. Bastard.
