- Hilarious in Hindsight: The joke about jingles being nicknamed "Pepsis" with no one remembering why has only gotten funnier with age.
- Romantic Plot Tumor: The romantic tension with Mary and the tacked-on, very Freudian/Electra-complex "true love" with Barbara, feel awkwardly shoehorned in (especially as the Happily Ever After resolution for the latter relationship is very much out of left field) and at times push Lincoln close to Jerkass territory for a modern reader.
- What an Idiot!: Ben Reich thinks he's come up with the perfect murder. Powell knows it's him almost immediately. Even without peeping- Ben's the only guest to call a lawyer while everyone else is in shock and knows that Barbara ran off naked. Although, if you take the psychology at the end seriously, this all ties in to his subconscious desire to be punished for the crime. When it looks like the police have failed he tries to kill himself, although not by conscious suicide.
