From primary school kids to footballers and celebrities - everyone's doing the mannequin challenge.
In case you've been banned from using social media for a few days it's the art of... standing still.
No need to learn a new dance routine, just strike a hilarious action pose and become a moment frozen in time.
James Corden, Adele and Beyonce have already attempted the challenge and we have a feeling there are more videos to come.
Presidential nominee Hilary Clinton released her mannequin challenge today.
In the last stretch of the US elections the video urges voters not to "stand still" when they could be voting.
And on Monday Radio 1 DJ Toddla T got the whole production team on board. In the earliest videos posted online, back in October, the song Black Beatles by hip hop duo Rae Sremmurd is playing in the background.
The song has since been named as the soundtrack to the challenge.
But it doesn't look like it's a viral promo for Rae Sremmurd - because they were late to the game.
Not until last weekend did they get the audience to stand completely still while they recorded their version of the challenge.
The trend started in American schools last month and has since gone viral.
It just looks like a "thing" - there's no campaign or charity element to it.
In the past we've had the harlem shake challenge, the ice bucket challenge and the running man challenge.
