With Las Vegas awash in the “Fight of the Century” media blitz, another smackdown of equally high stakes and frothing anticipation flew cooly and surprisingly below the radar. Of course we’re talking about the second annual international Museum Dance Off, in which Las Vegas’ National Atomic Testing Museum decimated three opponents in the first round, leading to a May 5 match against the Canadian Museum of Immigration at Pier 21 that had fans voting early and often.

The Canucks threw it down to “Safety Dance” in hard hats and safety vests (even a mascot!), but had this to face: the Atomic Testing Museum blowing it up to Imagine Dragons’ “Radioactive,” a song practically written for the Smithsonian-affiliated institution.

With 28 international museums participating in the video/dance contest hosted by the humor blog whenyouworkatamuseum.com, the competition had staffers in period garb shakin’ it in historic sites to “Turn Down for What” and Lady Gaga’s “Applause.” But with gas masks, an alien, a fallout shelter, Geiger counters and a multigenerational cast grooving and riding a B53 thermonuclear bomb, the rest of the field could only be pitied.

Unfortunately, the Canadian museum got 12,707 votes to Atomic’s 10,340. Ka-pow.
