I'm late behind the curve, as always, when it comes to picking up Internet fads... here's the newest one I found, called Animutations. These are just perfect for my warped sense of anti-humour :-) Most tend to be Flash animations consisting of images of pop-culture icons dancing around to music, mostly of Japanese or German origin. Most tend to make fun of the Engrish common in J-pop tunes, or else they use a variety of nonsensical Mondegreens. Yeah, I know, it doesn't sound like much, but you have to try a few! The very first one I saw is called We Drink Ritalin... would you believe that's Engrish for "Wishing, Revealing?" lol!
The funniest one has to be Wizard Power: Einstein must die!!!
Special mention for Holy Shit!!! Ninjas!, although it may not seem too funny for non-gamers.
A really quick one is Asian Pride, short, sweet and funny as hell!
