If you're up on your internet trends, you've seen the new mania over the Mannequin Challenge — which, if you haven't heard, is a thing that shows off people's talents for standing really still...for a really long time.

The cast of Hairspray Live! stopped the beat for a few minutes to take the challenge, and passed the test with flying colors. But of course they had to celebrate their success with some fancy dance moves.

Hairspray Live! airs on NBC on Wednesday, December 7, at 8pm.
