This newlywed couple really doesn't like dancing and wanted to get it over as quickly as humanly possibly. Which is why they settled on the extremely brief, just-over-one-second Napalm Death track "You Suffer". The couple jokes in the YouTube video description that "'Allowing The Carvings For Mutual Compassion' by Last Days of Humanity was a couple seconds too long", which if you're unfamiliar is a whopping seven seconds.
Congratulations to the bride and groom!
