A series of animated shorts that I saw in the 90s. I remember one scene had a pair of twin brothers who took turns abusing each other. It started with them taking turns slapping each other and then escalated. One painted the other’s head to look like a baseball and then knocked it off with a bat. Then after his head grew back, he put seeds on the first brother’s head and watered them until they grew into grass and the rolled over his head with a lawn mower. It was slapsticky as opposed to gory.
