- A sign on the door identifies the doctor's character as Dr. Legs Akimbo. However, this isn't visible in the finished episode.
- The Red Dwarf VIII Script Book shows that Doug Naylor had originally intended for the Monkees song "Take a Giant Step" to accompany the four Dibbley characters stepping into the corridor and walking together in unison. This sequence was shot, and when clearance was not granted for the use of Monkees music, the song Little Green Bag by George Baker Selection, best known for its use in Reservoir Dogs, was used instead. this song is also used in the DVD extras of the series 2 featurette "Alternate personalities"
