Humor is a uniquely human trademark and it's used to camouflage many things, including horror. Comedian Gilbert Gottfried (the voice of the duck in those ubiquitous AFLAC insurance commercials) was fired by The Martin Agency after he tweeted not so funny things about Japanese earquake and tsunami victims. We thought we'd take a look at some other famous commercials which also starred animals. A handful of them feature cats and dogs. See if you remember: Morris The Cat, The Taco Bell Chihuahua, and Spud's MCkenzie, to name three.
