- Acting for Two: Technically it's one on-screen role and one voice role, but Kevin Allen plays the French waiter and also provides the voice of "Cannonball" Taffy O'Jones in "Finger".
- Actor-Shared Background: There was a recurring gag in the show, which Eddie was asked if he was related to Adolf Hitler and Eddie would reply "Yes!" and had thought that his mother's name was Adolf, although Eddie had been abandoned as a baby. In real-life, Adrian Edmondson's father was named Adolf.
- Completely Different Title: In Spain the show was known as La pareja basura (The Trash Couple).
- The Danza: Richard Mayall and Adrian Edmondson.
- Distanced from Current Events: The camping episode ("'s Out") was omitted from the original 1992 run completely due to a then recent murder on Wimbledon Common; it was eventually aired in 1995.
- Dyeing for Your Art: Ade Edmondson shaved his head to play Eddie.
- Inspiration for the Work: The series was developed while Rik and Ade planned their West End production of Waiting for Godot at the Queen's Theatre. The idea was to create a Spiritual Successor to Samuel Beckett...with swearing and knob gags.
- Irony as She Is Cast: In the series, Eddie can't cook to save his life (he once resorted to eating lard when he was hungry) and has to rely on Richie's terrible cooking. In real life, Adrian Edmondson is actually a very talented chef who won the 2013 edition of Celebrity MasterChef.
- Out of Order: The third episode, "Contest", was supposed to be the pilot. The noticeable differences are in the set with the organ being on the "fourth" wall, stairs opposite way, and the fact Richie has shorter hair than usual as well as Eddie visibly showing hair and missing his sideburns indicate that this episode was filmed much earlier than the other episodes in the series.
- Real Song Theme Tune: The series uses "BB's Blues" over its opening credits, and "Last Night" over the closing credits. Both covered by the show's house band, The Bum Notes.
- Throw It In!: Rik Mayall accidentally hit Adrian with a Groin Attack on The Big Number 2 stage show. Adrian's next line is "It's alright Richie, I have 3 fucking kids already."
- What Could Have Been:
- There were plans for a fourth season, which would have continued by revealing that Richie and Eddie getting gunned down by the SAS at the end of "Carnival" was a dream (mocking Dallas). Another option was to have Richie and Eddie simply survive their shot-wounds, and let the show continue as if nothing has happened.
- Over the years, Rik Mayall and Adrian Edmondson repeatedly considered to return as their Bottom characters. According to Edmondson, one of those ideas involved an elderly Richie and Eddie living in a retirement home, "[where] we will be hitting each other with colostomy bags". This idea never came to fruition when Mayall died in 2014.
- There was talk of a Sequel Series based on the duo's Hooligan's Island stage show that would have had them stranded on an island.
- Working Title: Adrian Edmondson and Rik Mayall originally planned to call the series Your Bottom - so that viewers would be heard to say such things as, "I saw Your Bottom on television last night".
- You Look Familiar: Helen Lederer pulls double-duty as a nurse in "Apocalypse" and as Richie's would-be bride Natasha in "Digger".
Lyrics to Richie's version of The Sailor's Hornpipe:
Do your balls hang low?
Can you swing 'em to and fro?
Can you tie 'em in a knot?
Can you tie 'em in a bow?
Do you get a funny feeling when they're hanging from the ceiling?
Oh you'll never be a sailor if your balls hang low!
How Eddies Special K competition entry really reads (after redactions):
I want to go to the Bahamas because
its bloody hot there thats why! What a stupid fucking question and besides theres lots of birds knocking about on the beach, wearing skimpy bikinis with their knockers hanging out, for everyone to get a really, really, really, really good look at!
