Children's silent comedy. Eric Shaffer, the school genius and sports champion, accidentally hands in a signed derogatory caricature of his teacher Mr Carkdale instead of the answers during an exam, and the rest of the episode revolves around his attempts to retrieve the sketch from Mr Carkdale unnoticed. Eventually the sketch is retrieved, in the process of which Eric sets off the fire alarm, but due to a series of accidents, the sketch is photocopied hundreds of times and the copies blown out of a window onto the playground where all the pupils and teachers are lined up below. Everybody sees the sketch and Mr Carkdale calls out the only spoken word in the episode: "Eric!".
