Farrah: (laughing) Mama look! He's climbing on her back! Hahahaha!
Me: Oh! Well, um, I think he wants a piggyback ride because they're going for a very long walk. He must be tired.
Farrah: That's funny! He's so much bigger than her and she's going to give him a piggyback ride? THAT'S SO SILLY! Hahahaha!
So, yeah, I had to find a clever way to explain away the humping happening on the screen. The male Wooly Mammoth was giving it to the female real good and I had to say it was a piggyback ride. Admittedly, I am grateful for the fact that I see the world as one big cartoon so that I could shut that extinct-animal-porn down as fast as I did. We were watching an "R" rated documentary and didn't even know it.
