Because of global WARMING, silly. You may think it's minus 10 out there, but Algore knows it's REALLY 120 degrees. It's all perception. Plus, all that hot air he's full of keeps him warm whereas we lesser humans have to rely on coats and hats.
Interesting about the coat, but then again, I’ve never seen a walrus wearing one either.
Hey, I know he and Tipper were the inspiration for “Love Story”. I wonder if Gore was also the guy the Beatle’s sang about? (”I am the Walrus”)
