I normally mess with them too. I also keep credit card people on the phone at home on the speaker phone as they discuss how good their card is. My standard response is normally, if it's that good, can the card be used to cut cocaine, and if I can launder money with it. I also ask if these normal day to day transactions can be hidden due to my frequent visits to the bunny ranch. At this point they normally hang up on me, never calling back.
