Joyce Caruso walks out on David Kokolovitz, our hero at the high-school prom. Her ex-beau, “Crazy Bernie” Shulberg, wins her back by his talents as the “Milton Berle of Theodore Roosevelt High.” After graduation, David’s smoldering resentment leads him to the Marlowe School for Performing Drama, so that he too can become an actor. He will show them! And so, in one short week, after hours delivering sewing machines for the Foreman Machine Works, David Kokolovitz becomes Don Coleman, actor. He attempts to learn the words and master the accent of an urbane young Briton in Mr. Prim Steps Out (“I realized that I unconsciously had been doing my C. Aubrey Smith impression instead of my Ronald Coleman one”); tries curing his optic reaction to finding himself on a stage, in front of live people (“My eyes had, without warning, subtly crossed themselves”); and enjoys fully the sudden change from pursuit of one reluctant maiden to pursuit by two full-blown, eager ones.
