Dogberry and Verges
Although they do not appear until the play is almost half over, the actors in the sub-plot have some fine scenes of bumbling comedy. Dogberry is a parody of the inefficient officer of the law. He loves words, but continually misuses them, and is so convinced of his own importance that no-one listens to him -- with the ironical result that Leonato misses the vital information they could have provided before the near-tragedy of the scene where Claudio violently rejects Hero.
