See four large teeth marks rising above skin level on the right cheek of the victim:

Notice the calm (sly) and peaceful demeanor of the attacker:

Let it be noted that today was the first "revenge" attack between brothers.

And it was fun to watch.

Everett was getting a lot of attention as he was "talking" to Grammy on the phone. Daddy Mock and Mommy Bee (ooh, that sounds fun, must keep those names) were so impressed with his ability to communicate to Grammy that Carter felt he needed to be acknowledged in the conversation, therefore out of plain impulse bends down to wrestle/play-bite Baby. Baby is mad that he interrupted his glory and proceeds to bend, grab, and bite Big Brother on the cheek.

It was awesome.

I wish we had it on tape.

Needless to say, Carter learned his lesson.
