Thanks to the social media app Tik Tok, old videos from years gone by have been popping back up and going hugely viral - just like this video of Grease's 'Greased Lightning' without music.
The video was originally released 6 years ago in 2015, and in 2021 has gone viral again after amassing millions of views on Tik Tok.
You may have already seen this, but it is 100% worth the watch again. And if you haven't seen it - you will want to! Watch it above.
