In my work, I have two rules-I don't do teeth or feet-EVER!

funny asian candid camera
 

it really gets amazing at about 1:50

This is probably going to come off as racist, but whatever...the mother at the end of the video looks like LaFayette from True Blood.

Haha 0:45

why do you like watching that stuff?

Well, I find the angry grampa just, funny?
Old guys getting angry, is right up there with people falling over for me.
Another thing I like is when people ALMOST fall over...just those momentary stumbles? Or, how people act when they have a bug or spider on them.
If something unintentionally makes you laugh you can't really explain it.

The other stuff, well, I mainly enjoy just subjecting others to it - though when I watch them, I do find myself laughing at how capable the human body is to fuck with itself.

That angry gandpa guy is pretty funny, I ended up watching a lot of his other videos.
