So what's the worst that can happen to an organist? Actually there's quite a list of embarrassing and bad things. Having the organ hit back with a stop knob malfunctioning is just one of the ways the organist can end up with mud (or an organ knob!) on their face. A cartoon shows a stop knob falling out of an organ while the horrified organist looks on, still trying to play. The words "Revenge of the organ" are written in red above the cartoon. The text "Organist nightmares #38" can be altered or removed if you wish.
