Grandpa, as depicted in Dad's shadow puppet.

Grandpa is a character mentioned several times throughout the series. He is the father of Dad and Professor Longhorn Steer, the husband of Boneless Grandma and the paternal grandfather of Cow and Chicken. Judging from many of Dad's descriptions of his father, Grandpa was likely a cross-dresser and very effeminate, a trait that is often shared by his own son. His only appearance was in the episode Perpetual Energy as a shadow puppet made by Dad's foot.
