A woman in Jilin, China, got her hand stuck in her boyfriend’s mouth while they were trying to film a video for social media. It went in fine, but when she tried to take it out the man's jaw muscles cramped, clamping down on her hand and trapping it. To get his girlfriend’s hand out, medical staff played calming music to relax him and used a special tool to slightly open his mouth, then gave him a muscle relaxant.
