For that matter, if a duck quacks in the forest, and no one is there
to hear it, does it really make a sound?

I can't tell (based on the setup) if this is a serious question or
not. ;) But if it is a serious question, "nil" at least responds to
the instance methods defined for any Object, since "nil" is an
instance (*the* instance) of NilClass, and NilClass is derived from
Object.
