7. Punching Horses
Before motor vehicles, horses were a primary source of transportation around the world. So it behoves us to look after them, treat them right, maintain that bond between us and them.
Unless... you're not feeling that way inclined towards our equine friends. Maybe you've been wronged by one, somehow. Maybe it overtook you in a street and splashed mud up your new chaps and you're feeling mighty sour about it.
Then, why not show that horse who's boss. No rolled up newspapers here, oh no.
Ball that fist up and give it the taste of a knuckle sandwich. That'll teach it, good and proper.
Except... it won't. You've just punched a horse in the face. Hope you feel proud.
