The sight of Danny DeVito dancing alongside the boys of One Direction just made our day.
The "Always Sunny In Philadelphia" star appears in the new video of "Steal My Girl," the band's lead single from their upcoming album "Four."
It's definitely a random gig for the actor, who can be seen busting a move with Harry Styles, Niall Horan, Zayn Mail, Liam Payne and Louis Tomlinson at the end of the clip.
But he may not even be the most bizarre thing about the video.
Shot in the desert, "Steal My Girl" also features appearances from sumo wrestlers, tribal dancers, a marching band and one very adorable chimp.
Just check out the video above. The band's new album is due out November 17.
