I wasn't able to find the original video or even a gif from it since youtube scrubbed the original and the gif was something I saw on 4chan about a year ago, but there's probably plenty of this kinda crap to find in the more obscure corners of the internet if you're willing to look for it and aren't as lazy as I am.

Here's an example of some of the stuff I'm talking about, although this example is somewhat mild compared to what I described before.
:Edit: I found a version of the GIF that has been cut off before he tried to do the really fucked up shit, I feel dirty now and I'm probably on a watchlist. I'm on kiwifarms though, so fuck it, I probably already was on a watchlist before.
and there's a few more here,
