Boneless Grandma is an old cow mentioned in "Cow and Chicken Reclining" and "Alive!". She is the mother of Dad and Professor Longhorn Steer, the wife of Grandpa and the paternal grandmother of Cow and Chicken. Judging from her name, she had no bones in her body, a trait which was apparently inherited by Boneless Chicken. When Dad was young, she gave him the family clock which had been passed down to every calf in their family for generations.
