Ah the things we'll do to get likes and build our social media following. In an effort to entertain her cousin, a Canadian high school student stuck a harmonica in her mouth. But then it got stuck. So naturally, she turned to TikTok to detail her plight. "Every time I breathed heavily out of panic, it made a noise," Mollie O'Brien told Buzzfeed. Watching the video, set to the song "I Just Did A Bad Thing," you can hear the harmonica playing. Fortunately, the story has a happy ending. Mollie's mom took her to the dentist to have the musical instrument extracted. He issued a warning: "Let's not do this again, OK dear?" What's the dumbest thing you've done publically?
