Plot

In this slapstick romantic comedy, the bumbling, but perpetually optimistic "natural-born salesman" Alexander Botts is egged on by his sweetheart Sally to do great things, so he writes a letter to the Earthworm Tractor Company, and is hired as a salesman despite the fact that he knows nothing about tractors. He gets fired more than once for all the destruction he causes, but is rehired by getting orders. After Sally abandons him as a failure and marries another man, he falls in love with Mabel, daughter of the cranky and partially deaf Sam, the owner of a lumberyard who believes he does not need tractors to clear paths for his lumbermen. Botts continues to enrage Sam via various antics such as moving Sam's house with Sam in it without telling him in advance and in the process destroying most of Sam's furniture. Eventually, he proves a super salesman by selling many tractors to Sam after he cures him of his deafness, and wins Mabel's love.
