In the Movie "for richer or poorer", about 1 hour and 15 minutes into the movie, "give or take", while Tim Allen and His wife are talking to the amish dude there are several cows in the background. If you pay close attention to the cows in the background one cow will get on his hind legs and get on another cows back. After about 7 seconds his mistress is tried of being "touched" and the hind leg cow dismounts! Now if that isn't two cows having sex then I dont know what in heck would be!
