Things got extraordinarily weird at this private Foo Fighters gig

Enterprise software giant Salesforce is known for bringing in big-name entertainment like Metallica for their Dreamforce event. This year, the music came from the Foo Fighters. As they roared through their set, they were joined onstage by some dancers. And not normal dancers, either. They were Astro, Einstein, and Ruth, costumed mascots.

And you thought this sort of thing only happened in Japan.
