This is a game I've seen done before, though whether it was on FTC or Facebook I can't recall. The only goal is to come up with ridiculous but more-or-less accurate descriptions of musicals. Feel free to do multiple descriptions of the same show.
For instance:
Sweeney Todd -- Trendy hair stylist takes on a partner and expands into the restaurant business. Hilarity ensues.
Follies -- Showbiz documentary with performances from all your favorite acts. Behind-the-scenes footage reveals the scandalous personal lives of music industry legends.
Pacific Overtures -- Japanese revenge for decades of racist caricatures.
Into the Woods -- Feature-length version of Jay Ward's Fractured Fairy Tales. Live-action sequences would have been greatly improved with the addition of muppets, but everything can be improved with the addition of muppets.
Promises, Promises -- The surprisingly scandalous origins of apartment time-sharing.
Sweet Charity -- A prostitute goes to work for the girl scouts helping to sell candy.
