The Tuba player was not originally intended to be a ghost, but instead just an annoying resident. He became a ghost when on set actors Elisha Reichert and Colby Fahrenbacher suggested it would be cool just to see him fade into the background. Klein was hesitant at first as they had just completed production on their Halloween episode and he feared the inclusion of a ghost may be bad timing. Morin convinced him to include the ghost and the ghostly tuba player is now an actual myth at I.S.R.
The speech where Daniel explains how to play Apples to Apples was actually written in early drafts of the script. Fearing that the scene would be too long, Morin told Klein that he would have Bob Dignan "wing it" on set and they could edit it down in post production. Dignan came up with two different explanations on how to play the game, neither of which had anything to do with actually playing the game, with both relying on obtaining the "Helen Keller" card. This card, Dignan said, was the trump card. The entire speech is actually used in the episode but played forward at 200x.
Producer Marc Morin Jr. hates the game Apples to Apples.
The dueling musician scene had been planed from the pilot when creator Derek Klein had been discussing the series music with guitarist and composer Alexander Hoyne. Hoyne thought the idea was amusing and so Klein contacted Fahrenbacher about appearing in an episode.
