 His name is Marvin Drey and he s come to Dog River to check up on a few things concerning Corner Gas after a rather heated phone conversation with Oscar. Thinking that his only way out of jail, (which no one said he was going to in the first place), is a zany ploy, Oscar enlists the help of, of all people, Hank. Kevin McDonald of "The Kids in the Hall" guest stars as Marvin Drey, the Tax Man. (Or is it A Tax Man?)
