I know I defined a singleton method for object a, but I don't quite
understand why I am defining a singleton for NilClass, by doing

def NilClass.method_missing...

Can NilClass be an object name rather than the Class NilClass? If I am
defining a singleton method, then, does the OBJECT NilClass has to exist
before I define the singleton method?

thanks,
Shannon
