Tom Lenk named this as his favourite episode. "I just got to make such an ass out of myself. It was so much fun. Dancing in a toga on a hillside singing with unicorns was pretty embarrassing. I don't do that sort of thing ever in my down time. So, I just had so much fun doing it".
The sequence with the Mutant Enemy mascot, the little monster that goes "Grr Arrgh" at the end of the credits, was changed a total of six times:
- in Becoming: Part 2 (1998) (#2.22) it said, 'Oh, I need a hug."
- in Amends (1998) (#3.10) it wore a Santa hat and bells were jingling.
- in Graduation Day: Part 2 (1999) (#3.22) it wore a graduation cap.
- in Once More, with Feeling (2001) (#6.07) it sang its "Grr Argh."
- in Storyteller (2003) (#7.16) it sang, "We are as gods."
- in Chosen (2003) (#7.22) it looked out at the viewers instead of looking straight-forward.
The episode was an experiment to see how the audience would respond to a show centered around Andrew, since the series was ending and they were trying to find a character upon whom they could build another spin-off show.
When the Scoobies pressure Andrew for useful information about the evil Seal of Danzalthar, Andrew tries to squirm out of it by asking instead for a "cool, refreshing Zima." Buffy replies, "No Zima!" and Spike says, "Shut your face about the Zima, just talk." Jane Espenson had some years before created the name "Zima" for the adult beverage while working for a marketing firm.
That famous piece of baroque music in the beginning (when Andrew imagines himself as as some kind of host in the style of Masterpiece (1971) is the first movement of the 3rd Brandenburg Concerto in G minor by Johann Sebastian Bach.
