There's only one thing moving in this Mannequin Challenge - the train that everyone is travelling on.
Christopher Blackburn captured this footage on the service from Leeds to Brighouse last night.
It's the latest in a long-line of Mannequin Challenge videos that have seen sports teams to politicians freeze to capture moments on camera.
Christopher told the Yorkshire Evening Post that he didn't know most of the people on the train but the festive spirit meant they all happily took part.
He said: "A few of us had been having a sing-song and everyone was in the Christmas spirit and it just happened."
