- Toward the end of the episode, while Robot was changing channels, we get a glimpse of various commercials from precedent episodes:
- This is the second time Punch Morley's short-term memory has been used for an advantage. The first time was in Speeding Ticket.
- This marks the second time Robot and Monster associate with children. The first time was in in Adventures in Babysitting.
- When Robot tried his second attempt with the bottled charm, we learn that Punch Morley is perhaps unmarried.
- This is the second time Loudmouth kicks Robot. The first time was in Biker Girls.
- This episode demonstrates how easily Monster makes new friends, beyond the ones he already has, and how difficult it is for Robot to make any new friends.
- Apparently, Monster's personality contributes to his height, as he was briefly small after Robot stored his "essence" in a jar.
- This marks the second time we see a tiny Monster, as the first time was during a hallucination of Robot's in Letterology.
- The child Robot tries to greet properly was seen in the later episode Bad News Baconeers.
(Monster gives Robot a few lessons in how to approach someone)
Monster: Next, give them a firm confident handshake.
Robot: (shakes his hand) Got it! (approaches someone reading a book and extends his claw) Put it there, pal!
(book falls and it is revealed to be Loudmouth)
Loudmouth: I don't have any arms, you insensitive jerk! (kicks him)
Sir Cranklin: Are you mad?! You just destroyed my blimp! you...(tone changes because of Robot's essence) Extremely likable fellow.
