Species: Human
Age: 73

== Characteristics ==

Marvin is Chas's father and Chuckie's grandfather. For the most part, he is very old-fashioned. He is married to Shirley. This is evident because of his lack of knowledge about the Lipschitz method of psychology, using "rabbit ears" to watch television, and not even knowing what cable is. He is the opposite of Chas and is a rugged outdoorsman type and in excellent shape. He tried to toughen Chas up when he was young but failed most likey due to Shirley.
