Tad and Kate. Kate and Tad. Hearing those two names together makes me happy. I think about plane crashes and the world coming to an end. I think about hobos, bad presents, karaoke and being kidnapped. I think about all of these things and I smile. It’s some kind of Pavlovian response. I’ve become so accustomed to being entertained by this duo that I just can’t help myself. At least I don’t drool.
