The Russians have two entries: PhotoExtreme is an offshoot of live-action role-playing games, as one would expect in the sort of hardcore place that Russia is fabled to be. In this meme, one person comes up with a bizarre scenario, and others act it out, take photos and post them online. The scenarios are acted out in public, without anybody being informed in advance, so bystanders are likely to be confronted with surreal, often violent (ontologically, if not literally) spectacles.
The other Russian meme is a more innocuous one, not unlike LOLCats, which originated from a rather naïve American drawing of a bear, and involves photoshopping said drawing into images. In Sweden, meanwhile, they do something similar with an image of a guy with a horse's head; this meme is named "Snel Hest" ("Nice Horse") and often involves horse-related puns. Meanwhile, the French go in for sarcastically 'shopping their self-aggrandising president Sarkozy into various historical scenes (it seems to be akin to the "Al Gore invented the Internet" meme of the 1990s) and in Australia, a video of a racist bogan chick went viral (the great Australian public doesn't really go for highly conceptual, it seems). The Kenyans, meanwhile, have a supercool tough-guy hero named Makmende, whose name comes from a mangling of Clint Eastwood's famous line "make my day".
