My sister Cathy and I always had this like phone joke. Whenever I see on my caller ID that's it's my sister calling me, I answer the phone with a little mean joke like: "Geez, I hope it's not my annoying sister Cathy calling!" or "I wonder if Cathy knows she's adopted."
Recently I've been getting bolder, as she quips back pretty good. So the last time she called, I picked up and yelled in this really rude voice: "BLOW ME, BITCH!"
Silence. Nothing. So after a few seconds I asked: "What's the matter, can't come back with anything?" Finally my sister replied: "Kenny, we're on a conference call with the IRS, and Mrs. Miller is on the line with us."
