| Biologically, there is only one quality
which distinguishes us from animals: the ability to laugh. In a universe which
appears to be utterly deficient of humor, we enjoy this supreme luxury. And it
is a luxury, for unlike any other bodily process, laughter does not seem to
serve a biologically useful purpose. In a divided world, laughter is a unifying
force. Human beings oppose each other on a great many issues. Nations may
disagree about systems of government and human relations may be plagued by
ideological clans and political camps, but we all share the ability to laugh.
And laughter, in turn, depends on that most complex and subtle of all human
qualities: a sense of humor. Certain comic stereotypes have a universal appeal.
