My uncle had a Pygmy goat, almost round he was so fat in the middle.
My uncle would tell men he loves to play. Put your boot on his horns and push him.
The goat would rear up on his hind legs and crash into your lifted boot.
After a couple time my uncle, now laughing, would say “try to stop”.
You could stop, but the goat wouldn’t. His horns reached almost waist high when he reared up.
