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.
