Repetition in comedy is very funny at times and other times not.
Nothing is more overdone, and nothing is more awful when it is
overdone. You can do a stunt just once too often and spoil the whole
effect. An assortment of crockery hurled with unerring aim and in quick
succession at a fleeing form provokes uncontrollable laughter that
increases with every plate that flies, up to a certain point. Beyond
that, the situation palls.
