Everyone is doing the Mannequin Challenge and no one is doing it better than The Late Late Show. They took their camera from the green room to backstage to the set for one epic 3 minute video of people standing still.
This challenge might not have a purpose but it is fun to watch!
BTW I hope no one shows this video to Craig Ferguson because I would be pissed if I was him. They completely redid that whole area. When Ferguson was there it looked like a dump and now it looks like all the other Los Angeles late night talk shows sets.
