This was the only episode in which Rodney would openly discuss with Trigger that his name was Rodney and not Dave as Trigger had hitherto referred to him (the first occasion on "Big Brother (1981)" two years earlier). Trigger used the name Rodney when voting him onto the committee but reverted to calling him Dave, even in the final episode "Sleepless in Peckham...! (2003)" twenty years later.
Renee Roberts plays Miss Gatsby and Gilly Flower plays Miss Tibbs. They played characters with the same names in Fawlty Towers (1975).
Dr. Becker would be mentioned again in "Thicker Than Water (1983)", as well as the first Rock & Chips (2010) episode "Pilot (2010)".
Vaslav Nijinsky did indeed grow up in Imperial Russia, although he identified as Polish.
Rodney and Dr. Becker are both left-handed.
