Being a sceptic with a C, I decided to check up on the story. I am pleased to report that it appears to be true:
Yesterday, I noticed a leaflet pinned to the health and safety noticeboard at work entitled Musculo-skeletal disorders.
It occurred to me that Musculo would make a great name for a cartoon super-villain—a worthy adversary for Superman™ or Spiderman™ or Batman™. So, indeed, would Skeletal.
I imagine Musculo must have fallen into a vat of steroids as a child, whereas Skeletal overdosed on weight-loss tablets having been spurned as a fatty by the woman of his dreams. These two embittered men have now teamed up to wreak Musculo-Skeletal Disorder throughout the world.
Note to Marvel™ and DC™ Comics: Let the bidding war commence.
