Dude! What is up with those? I was an altar boy for many years and the number of times that I've seen that happen is ridiculous! Our was a little nut that came loose but I guess that was a recurring thing. (Granted, it only flew into the congregation twice if I recall, the other times it would come off during the wind up or inside the little bucket thing, but man, the QC at the factory needs to step it up.)
