Mailbag: "Does Alan Kalter really have a twin?" Dave points out that he does have a brother named Rick, but Alan interrupts with a chin rub. Apparently, Big Red recently discovered he has a twin sister, Denise. After catching up on lost time at a local restaurant, Alan and Denise go to his place and make out.
