When I was kid in the 70’s we drove cross-country one summer in an Econoline van with no seats in the back much less seat belts (we had a trunk with a blanket on it), and the AC was a spray bottle of water, and we liked it.
My uncle had a large German Shepherd and was expecting his brother, who the dog loved. He heard a knock and opened the door as he jokingly said “Truman, kill!” Cut to two terrified Jehovah’s witnesses running away.
I think he had just approached it and hadn’t started yet.
