KVN is a show on Russian TV that asks comedy troupes - mainly students - to perform their sketches, skits and stand-up routines in front of a live audience and a few judges.

As you might expect from this cross between Saturday Night Live and Britain's Got Talent, the results are often... patchy, to say the least.

But every once in a while, there's an absolute gem that transcends the normally limiting effects of the Russian language - and this is one of those gems.

Discover the world's worst/best/weirdest cover of Finnish hip-hop Bomfunk MC's 1997 hit Freestyler, as performed by five female students and, eventually, a few guys riding in with cardboard Alsatians pretending to be SWAT squaddies. As you do.

And if you were wondering what the original sounded like - and you're willing to have it stuck in your head all day - here it is for you below, in stereo. Okay, the stereo thing depends on your speakers/headphones, but there you go.
