A joke about bad internship jobs taken to an extreme. These two interns act doing the menial task of holding in/out paperwork, which could easily be accomplished by a simple file folder or shelf. Accordingly, another job that could be done by a human that's usually done by an inanimate object is  holding up clothes like a coatrack. It's funny to think of how bad these people's internships are, which plays on the thankless nature of real internships in the real world.
