The episode "Murray Christmas." Rallo meets an elderly Jewish man who's racist and Rallo makes anti-semetic comments. To teach him a lesson, Rallo's teacher makes him spend time with Murray. Being an old man and a young boy, they can relate due to having to wear diapers and early bedtimes. The ending where Rallo gives him a menorah and a dreidel for Hannukah was real sweet.
