In this classic episode, Beaver has been grounded in his home for the weekend as punishment for tampering with his father's things. However, on the coaxing of Larry he goes out to the movies and - as luck would have it - wins a brand new bicycle in a raffle. How will he explain this situation to his parents, who think he was home the whole time?
Jerry Mathers is on record comparing LITB to a "medieval morality play" and the character Larry Mondello to Beaver's "Tempter." These are apt comparisons; just look at the way Larry is never without his shiny apple! LITB also excelled at depicting the causality of evil. Very often it's a brief decisive moment in time, a simple word or gesture or bit of carelessness on Beaver's part, which starts a domino effect leading to his getting in trouble. Here we have the added irony of Beaver's winning a bike in a raffle - an event which normally would be an occasion for celebration but here is cause for dismay!
In the closing scene, the story opens out into deeper territory as Larry wonders whether God was punishing Beaver by making him win the bicycle. There is also a subtle differentiation between Beaver's character and Larry's: Beaver declares he would never do to Larry what Larry did to him.
In sum, one of the more memorable moral tales from the series and one which shows Beaver's staunch character and innate sense of right and wrong.
