The first episode James Burrows did not fully direct because he caught Walking Pneumonia.
In later episodes, Lilith would be an observant Jew (like Bebe Neuwirth, the actress who plays Lilith), but in this episode, Lilith celebrates Christmas with the rest of the Cheers gang.
Two actors would later play the same Christmas roles that they played here in a movie. Kelsey Grammer, who plays Frasier as a Scrooge type character, would later play Ebenezer Scrooge in A Christmas Carol: The Musical (2004). George Wendt, who plays Norm as a mall Santa, would later play Santa Claus in Merry In-Laws (2012), alongside Shelley Long, who played Diane Chambers, as Mrs. Claus.
Norm is shown to be working as a department store Santa Claus. George Wendt would later play or depict Santa Claus in a few made for TV/Direct To Video movies, late night talk show skits, and in a stage musical adaptation of Elf.
