Personally, we've never seen someone pull off a successful birthday cake face-smash. It's kind of like a double rainbow or a full water bottle flip -- it just doesn't happen in real life! And when it does, it's...depressing. Who wants to watch someone's birthday get ruined?! (Apparently, entire cultures. Cake smashes, or "la mordida," are a Mexican birthday tradition and are actually a sign of endearment. Who knew?)
