God bless you, people of Mencap. Both for the sterling work you do for those with learning disabilities, and for being the first set of British office workers - as far as we know - to upload your version of the Harlem Shake.
Yes, the internet may be awash (and it will soon be flooded) with Harlem Shake videos, but nearly all of them (see the collection below, for example) have so far been made by Americans. Yes, even the cats and dogs ones. They're still American cats and dogs.
So hoorah for Mencap, and their very brilliant video above. If you want to find out more about the charity's work or get involved, just check out their website. Strikes us as a rather brilliant place to work...
