- Hilarious in Hindsight:
- When Kryten is transformed into a human, he has difficulties with what he has lost and gained in the transition from mechanoid to human, and hands Lister a polaroid of his penis to see if it is normal. Lister's reply of "Is it normal to take pictures and show 'em to your mates? No, it's not normal!" is funny enough originally, but when one remembers the rise of dick pics on the internet and smartphones in the late 2010s it becomes side-splitting.
- The conversation about wanting to be a squirrel was pretty funny at the time. A few decades later after the rise of Furry Fandom it's smegging hysterical.
- One-Scene Wonder: Spare Head 3 only appears in one scene of this episode, but his ludicrously Northern accent make him very memorable.
