I believe that's DJ Pauly Polka in the center, rocking the first ever blowout. And there's Claus Von Situationsteinn right up in his grill - a truly epic moment in photography capturing the original Bavarian Beat Battle.
To be honest, with all the Jersey Shore parodies and spoofs we've seen, I'm actually shocked we haven't seen a Fist Pump Polka from the king of all parodies. I would gladly pay money to see this happen, especially since I haven't already paid to see Weird Al in concert twice in my life. Nope, definitely never did that....
