Boneless Grandma is a character 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 girl in their family for generations.
