a city man is driving on a back country road from town when around the bend comes a woman driving a truck, she leans out her window and screams at the man... PIG!
well, not to be out-insulted by this backwater female he leans out his window and yells back to her COW!
feeling quite satisfied with himself, he pulls his head back inside his window and looks forward just as he SMASHES into a large hog standing in the road.
the city man calls AAA and has his car (no mention of what car it is, but let's just assume it is a Mercedes) towed back to town.
on the way back, the lady is just getting her truck hooked up to a tow cable to pull her out of the ditch she slid into... apparently trying to avoid the aforewarned bovine impediment.
