This seems like a sensible way to ensure that the number_of_cliches method always returns zero, but will it actually work? To put it another way, can you override a method in a module by defining that method in the class that includes the module?

Since we know that the methods in a superclass cannot override the methods in subclasses, we can deduce that not module method I read and highlight
