During the band's closing set, frontman Win Butler announced that Daft Punk was there to perform their hit "Get Lucky," which Arcade Fire started playing. But, what Butler really said according to those in attendance was "Paft Dunk."

Those two people in Daft Punk-like robot suits who walked out, well, they weren't really Thomas Bangalter and Guy-Manuel de Homem-Christo. They were just some guys in robot jumpsuits, which, when you think about it, probably isn't that weird to see at Coachella. The band's little prank though led to some really excited tweets and more than a few Instagram videos.
