Your entire wedding party, lip syncing the same song, badly, over the course of the day. And it turns out to be the best thing you own from it.
A crew films everyone miming to a track you choose. Bridesmaids getting ready, the groom and his mates outside the church, grandparents in the garden reluctantly mouthing along, the whole dance floor going for it at midnight. It’s cut together into a single music video where your song runs from morning to night and the cast changes with it.
It’s daft and everybody knows it’s daft, which is exactly why people commit so hard. The result is four minutes you’ll watch far more often than the official film.
