OK, here's a little test. Who is smarter in this scenario?

I was visiting my neighbor this morning, and his 20-something son and GF were there with their brand new freshly purchased labrador puppy. Apparently the kids think puppies are born understanding the English language, because I observed them saying repeatedly over-and-over to the puppy, "Sit! Sit! Sit! Sit!", ad infinitum. Of course the little lab was standing up on all fours, panting happily, looking at little birdies flying overhead, and at the son and GF, quizzically cocking his little head back and forth. After a few minutes of this, the kids shrug to each other, give up, pick up the little dog, and go trotting off down the street.
