This video cracks me up. You wouldn't think one kid biting another kids finger could be funny, but you'd be wrong.

I'm not sure if this has been on funniest home videos or not, but it probably deserves a spot.

What gets me is that first up, the kid sticks his finger in there and realizes it hurts a little, but goes back for seconds none the less.

If nothing else, this clip proves how resilient kids can be.

As with anything clean and innocent, there's always someone out there capable of taking it straight to the gutter. Hence, this adult themed remix... consider that your warning...

So unclean...
