The episode 'Frowning Friends' had a very troubled production and was the last to be finished, which resulted in several humorous oddities such as Mr. Man's head shifting into D.J. Spit's head at the end of his scene as the creators couldn't figure out how to end the scene and the Renaissance Men were a very late addition as a way to kill off Grim and Gnarly. Also, D.J. Spit was originally going to have visible pubic hair due to his low pants, but this was erased by the censors in the broadcast version.
Zach Hadel said that if he had the time to figure out who had censored the hair, he would have credited them as 'digital pube remover' in the episode's credits.
