RadioShack: "You've got questions, we've got dumb looks."
or:
"You've got questions, we just want your zip code."
I always say '90210' in response to that question. If they give me a nasty look, I follow it up with: You don't recognize me?
A gent from Comcast knocked on my back door this morning. He said if I was a man who actually lives up the street in the next block. I told him the fellow he named was in the next block, and pointed the direction. So what did he do? He leaves my back door and knocks on my side door. I open the side door and sez "I told you the next block, not next door." He turns away with a puzzled look and walks back to his truck and drives away.
"you've got questions, well so do we"
