teeth

Unless that was the point. 

IS IT LOST!?!?!?!

"Beau had two loose teeth he's been talking about pulling forever. Finally we tied floss to them and a chair, put him on a hoverboard, and he planned to go backwards really fast. His older brother Tate was filming and decided to just pull the floss and get it over with because Beau was taking too long! We're happy we captures Beau's reaction of pure excitement, nervousness, and then worry that we lost his teeth!"

Don't worry folks, nothing gross or painful here. It even has a happy ending!
