Because it's Friday, Man Bites Dog

I know, I know. It's a tired cliche. But what do you want from me? It's almost the weekend.

Regardless of how many times it's been done before, this kind of story still brings a smile to my face.

The AP has the tale (not tail -- double-ugh) of a pit bull that attacked an 11-year-old Brazilian boy, only to have the tables turned.

The boy bit back, sinking his chompers into the pooch's neck.

Here's the kicker: The kid bit so hard, he lost a tooth.

Which tooth, you ask? A canine, of course.

I'm not kidding.
