I'm sure you've seen videos of best men or grooms fainting at a wedding, but I can guarantee you've never seen one take a header like this.

It all went down during an outdoor wedding ceremony in Snohomish, Washington, which is north of Seattle. He smacks the pavement really hard like an albatross trying to make a landing, and he might have knocked out some teeth.

It's not clear how long he was unconscious, but it also looks like he peed his pants while he was out of it.

And I can't leave without asking why in the world would you let that girl sing at your wedding?! She couldn't find the song key if you handed it to her.

This video is NSFW.
