Anthony Wilford Brimley (born September 27, 1934) is the quintessential Grumpy Old Man, and also an American actor. Instantly recognizable due to his large mustache and rotund physique, he first got involved in the film business in the 60s, being initially employed as a horse shoer and occasional stuntman. His first acting role came in 1970, when he was cast as recurring character Horace Brimley in The Waltons. Since then, he has appeared in several movies and TV series. Notable film roles include Ben Luckett in Cocoon and Dr. Blair in The Thing (1982), where he appears mustache-less. From 1986 to 1988 he starred in the NBC drama series Our House.Well known on the Internet for his appearance in a series of memetic commercials for Liberty Medical Diabetic Supplies, in which he infamously pronounces the disease's name as "diabeetus". Ironically, he had previously been a spokesman for Quaker Oats, where he proved that he knows how to get a kid to eat its goddamned oatmeal.
