The guy who fell on his face in this video wrote about what happened on Reddit… and apparently he messed himself up pretty good:

”Pastor said he was going to give a 'quick' 20-minute sermon that became 40 minutes. I had a terrible breakfast and next to no sleep, I locked my knees and shortly after woke up on the floor. I broke my nose, dislodged my front teeth, and messed up my jaw pretty bad.”
