As a first step on his way to the top, Harry applies his genius to bakery van sales. Who better to show him the potential, pitfalls and perks of the round than would-be country and western star, Don 'Doughboy' Hudson?

Having been 'promoted' to office duties to keep him out of trouble, Harry finds that his genius is not being fully exploited and his only real challenge is facing the endless tedium. Until, that is, he mistakes the company chairman for a cleaner and joins him in a rather over-large brandy.

Harry is introduced to the tough world of salesmanship by pill-taking Mr Johnson. Will he now, at last, be able to put his genius to good use? What will he do for the bakery's sales? What will he do for Mr. Johnson's ulcer?
