Telemarketers. I get the calls from Rachel of Cardholder Services during work hours. So the best I can respond is a high pressure sales pitch for Brawndo the Thirst Mutilator (c). Otherwise I might actually ask for Rachel and ask NSFW questions about her.
“Hey Rachel....you sound kinda sexy. What are you wearing right now? Why don’t you give me your address and you and I can hook up later. Are you into spanking?”
