Weihnachten steht vor der Tür. Familie Smith ist voll im Feiertagsmodus. Allerdings bleibt Roger außen vor. Das verärgert ihn so sehr, dass er mit Snot Hanukkah feiert und zum Judentum konvertiert.

It's Christmas time again in Langley Falls and the Smith family is totally consumed by the impending holiday, except for Roger who is upset that he being overlooked in favor of the festivities. Feeling unappreciated, he goes to Snot's house where he finds a kindred spirit in the Jewish boy, and learns all about Hanukkah, leading him to convert to Judaism. Later - in a twist of fate - Roger puts on dead Santa's suit and turns himself into "Schmanta," a Jewish version of the beloved holiday symbol. Soon, thanks to Schmanta magic, everyone is celebrating Roger's extreme - and perverse - version of Hanukkah, and it takes an unlikely alliance to set things right again.
