- This episode is considered as the sixth season episode, although Kate Higgins dropped the role of Carmichael after the sixth season premiere "Gordon Gordon" seeming that the episode aired out of order.
- Because he only appeared in a couple of seconds, Professor Jirafales does not appear in any of the credits.
- This is the only episode where someone other than Janice Kawaye voices Ami. Although Kawaye was hired to still voice her in Mexico, which explains why she switches from Spanish to Japanese.
- Franklin/Nono only had one line in this episode.
- This episode was commonly selected for Comic-Con and animation conventions because of the poor animation style (pencil-and-paper instead of Flash animation) and the voice acting taste.
