A ''Simpson''-ized parody of ''Theatre/MyFairLady'' sees Lisa training the brash Groundskeeper Willie into being a proper gentleman; Homer sells his body as a human billboard to save his trademark blue pants from being discontinued.

!! Tropes:
* RagsToRiches: Willie ''looks'' the part and is very much praised for his new attitude, but soon, the snobs of the higher class start to annoy him that he eventually reverts back to his former self, not without thanking Lisa for thanking her time with him.
* ThingOMeter: One of the projects presented at the science fair is a surprise-o-meter.
