Ronda Rousey was filming an episode of the Fox TV show "911" and lost part of her finger! She was filming a scene where her finger was smashed by a boat door. At the time she just kept going until the scene was over and then looked down to see half of her finger just hanging there. (Trying to not throw up while I type this).
She was rushed to the hospital where the Dr was able to put her finger back together again. THEN she went back to the set to finish filming the next day. She's a machine!
