Two kittens try to squeeze through a small hole in a cardboard box at the same time. They're babies, so they don't know it would be more efficient to take turns. But soon you'll see that taking turns doesn't amount to much when you see how many more kittens there are!
And they kept coming. I was beginning to think that some human was putting the kittens back in the box out of camera range, so we'd keep seeing the same kittens go through the hole. If not, there are ten kittens. -via Tastefully Offensive
