Donald, Kim Jung, and Vladimir Dance Party?

A video of someone dancing in an ultra-realistic Donald Trump mask is blowing up on Facebook.  Another person is in a Vladimir Putin mask . . . a third person is in a Kim Jong-Un mask . . . and they're all dancing to "Uptown Funk".  

It's from a convention that happened near L.A. over the weekend called Monsterpalooza.  They're by the same guy who went viral last year, after someone bought a Tom Brady mask from him and wore it to a Patriots game.
