The West Ham United Twelve Days of Christmas gets underway today with our first festive video.
We paired Marko Arnautovic and Sam Byram for the Claret Crackers challenge - and who could come out on top in the battle to stifle their laughter.
It's two players, a bunch of Christmas Cracker jokes and a simple goal: Don't laugh!
We'll have more exclusive content for you in the run-up to 25 December, bringing together the best moments as first team stars spread festive cheer in the community, along with more Christmas challenges.
