Arnold Mavis Seanrick (born October 14, 1947, died September 21, 2000) was the hard-working, selfless, and smart brother of Eric and Norma, and the twin of Jerry Seanrick. Not much is known about him since he is deceased. He bore a striking resemblance to Diesel Dawson, except Arnold had pink eyelids, glasses, and a mustache as opposed to a goatee, but otherwise they were the same. He is Diesel's uncle because Norma is Diesel's mother. He was also the uncle of Lawrence Dawson and Simon Dawson. Jerry looks almost exactly like him except Jerry doesn't have glasses and has a goatee as opposed to a moustache. He died of a heart attack.
