One of those rare animations that made me laugh. Honestly dude, this is original as hell, so well done...
Only issue that puts down the animation is that the voices need a bit more love, (but then again, it makes it a bit more funnier in some cases, other then the black guy, he's voice sounds like there's static in it. [yes, I realize that sounds a bit racist; it's not meant to be >:P])
But honestly, that is overshadowed by the punchline and the cringing effect that Russian Roulette has. So yeah, well done.
