SpongeBob hallucinates actual Korean words on the gearshift of the boat, which really mean "forward" and "reverse."
The line "Oh, my aching tentacles!" is back on air in America. Some countries still banned the line.
At the end of "Pizza Delivery", Squidward saying, "Oh, my aching tentacles!" is now cut when the screen goes black for television airings. This is due to the closeness the word "tentacles" shares with one not appropriate for children.
In "Pizza Delivery", the idea of SpongeBob and Squidward going on a road trip was originally the idea of Stephen Hillenburg, inspired by the film Powwow Highway (1988).
"Pizza Delivery" is the first time SpongeBob wears his Krusty Krab hat throughout the entire duration of the episode.
