Nobody really knows what happens in Cats. There are … Jellicle cats? And they have names like … Rum Tum Tugger, Mungojerrie, Jennyanydots? And one of them gets to go to … the Heaviside Layer? Anyway, Stephen Colbert and Broadway legend Sutton Foster staged a very literal Cats parody on his show last night, which, because it had songs about things that cats actually do (like vomit!), makes more sense than Cats. It also does not make any sense. So it goes.
