Catchphrase: "He who dares, wins!" and "This time next year, we'll be millionaires."
Crooked Contractor: He has been known to dabble in this when the market trading isn't going so well. In the episode "Who's A Pretty Boy Then?", after stealing the job of painting Denzil's flat from Brendan O'Shaughnessy, he then offers his services when Mike says the brewery want the pub painted. Mike says Brendan has already put in a bid of a thousand pounds. Del immediately offers a counterbid of two thousand pounds.
Mike: Hang about, hang about. Why should I turn down an offer of £1000 and accept one of £2000? Del Boy: 'Cos of all the advantages it has to offer, like my unique profit-sharing scheme. The two thousand pounds would be disbursed thus: Five hundred pounds for vous, and five hundred pounds for ve. Mike: What, you mean I get five hundred quid? Del Boy: Oh, yes. Mike: And what about the thousand that's left over? Del Boy: We give that to the Irishman and let him do the job!
Also done in the famous episode "A Touch of Glass". Del and company offer to clean some chandeliers at a wealthy lord's mansion, and most obviously don't know a thing about how to do so. Cue Falling Chandelier and hasty retreat.
Everything Sounds Sexier in French: Would-be yuppie Del Boy is in the habit of throwing French words into his sentences even though he doesn't know what they mean. A full list can be found here.
Guile Hero: Del occasionally demonstrated enough savvy to come out on top after a whole episode of apparent failures.
Jerk with a Heart of Gold: Del Boy is self-centred, boorish, uneducated, a social climber (and a totally incompetent one at that) and a petty criminal, but he does genuinely care for the people he loves and has been shown to be quite sensitive at times.
Embarrassing Middle Name: Rodney Charlton Trotter. At his wedding, the audience can't stop laughing at it so it ends up being omitted from Cassandra's vows. Made all the more embarrassing by the fact that, despite Rodney's insistence that his middle name was inspired by Charlton Heston, it actually came about because his mother Joannie was a fan of Charlton Athletic F.C.
Heroic BSOD: Went through a fortnight-long one after Cassandra miscarried in the second episode of the 1996 Christmas trilogy, "Modern Men", until Del helped him get over it in the third chapter, "Time On Our Hands".
Identical Grandson: In the 2003 OFAH Christmas special and final episode "Sleepless in Peckham", Rodney discovers through an old photograph of the 1960 Jolly Boys' Outing that his biological father is not Reg Trotter, but rather gentleman thief Freddie "The Frog" Robdal.
The Character Died with Him: When Lennard Pearce died, they decided to kill off, Granddad (off-screen, of course). Thus the first episode made after Pearce's death begins with Granddad's funeral.
Cordon Bleugh Chef: His habit of utterly carbonizing anything he cooks leads to Del and Rodney eating out as often as possible. After Grandad dies, it turns out that Del is actually a fairly competent (if rather limited) cook, but let Grandad handle the Trotters' cooking just so that he wouldn't feel useless.
The Character Died with Him: Like Grandad, Albert was killed off after his actor Buster Merryfield died. Although Albert died during the episode, with the first scene explaining that he hadn't joined them in the Caribbean because it had turned out the great sailor didn't have a passport.
Dreadful Musician: He certainly isn't the best pianist around, but Mike tolerates his piano playing on the grounds that it prevents people from noticing that the Nag's Head's jukebox has been broken for years.
Flopsy: In the episode "Hole in One" he used a variant; using his parachute training to fall safely down open pub cellars.
Inflationary Dialogue: In the episode "He Ain't Heavy, He's My Uncle", he arrives at the flat with a black eye and no money. He says he's been mugged by a gang of youths, but the number increases every time he tells the story. It turns out he lost the money playing dominoes, and then got in a punch-up with his opponent Knock-Knock over Marlene's mother.
Suspiciously Similar Substitute: For Grandad. More blatant in his first few appearances, in which he was just filling the role that Grandad would have filled if not for Lennard Pearce dying, but he soon started to be portrayed as being more physically capable and less of a Cloud Cuckoolander than Grandad, along with his navy background playing a more important part in episodes.
Rachel "Raquel" Turner
Hooker with a Heart of Gold: In the 1988 Christmas special "Dates", Raquel Turner was introduced as one of these. She wanted to be an actress, but could only get not-real-acting jobs like stripogram or (in her second appearance) magician's assistant. After meeting Del, she gave up this profession after a Stripper/Cop Confusion at Albert's birthday party.
Straw Feminist: While generally not too obnoxious about it, she does have a habit of ranting about how all men have it easy in life, and how only women ever truly suffer (though after watching her give birth, Del does kind of see where she's coming from on the second point).
Women Are Wiser: To much less of an extent than Raquel, though. She's definitely the more sensible one out of her and Rodney, but Rodney is himself generally more sensible compared to Del Boy, and Cassandra is both insanely career driven and prone to acting like a spoiled brat at times.
Damien Derek Trotter
Enfant Terrible: Parodied — Rodney is convinced that his nephew Damien (the name is not coincidental) is one of these, and acts as if he's with the Anti-Christ anytime he's in the same room as him. The boy's just a normal child, but try telling Rodney that.
One particular scene highlights this; Damien wants to show off a conjuring trick he's learnt, and chooses Rodney to show it to. From Damien's point of view, he's just happily playing with his uncle. Rodney, however, looks as if he's being forced to participate in some kind of satanic ritual.
Informed Attractiveness: While Joannie is decent looking, the sheer amount of gushing she gets over her looks, from pretty much everybody, is somewhat disproportionate.
Running Gag: Whenever Del wants Rodney to do something for him, he always brings up what Joannie said to Del on her death bed. This was lampshaded in the fourth season OFAH episode "It's Only Rock and Roll" when Rodney tells Del about a row they had on whose turn it was to go and get the fish and chips, and Del claimed that Joannie said on her death bed, "Send Rodney for the fish."
Sympathetic Adulterer: Reg is neglectful, crude, abusive, and all too happy to sit at home, watch Joan bring home the bacon and then waste her meagre wages down the pub. Is it any wonder she jumps into bed with Freddie Robdal - debonair and attentive, if somewhat unreliable and immoral - the first chance she gets?
Too Good for This Sinful Earth: Del considers his mother Joan as having been an example of this. Subverted big-time in Rock and Chips where it's revealed that Joan was nearly as devious as her son—if a bit more kind-hearted—and not only did she have an affair which resulted in her becoming pregnant and giving birth to Rodney, she used Rodney's birth to secure the family a better home in Nelson Mandela House.
Even before Rock and Chips, it was obvious just how oblivious Del was to what type of lady she was. Such as how Joannie was the first woman in Peckham to smoke menthol cigarettes, how she was often to be found in the corner of a pub with two geezers and of how she used to buy her school aged son alcohol in pubs.
The Ghost: Marlene Boyce for the first three seasons. She was frequently mentioned by the characters, usually to wind up her husband Boycie by implying she'd really got around, but made her first appearance in Season 4, episode 5. Luckily they hadn't quite built her up to the point where no-one could play her.
The Other Darrin: Played by Jim Broadbent in "May The Force Be With You", the 1985 OFAH Christmas special "To Hull and Back", and "The Class of '62", and by Calum MacNab in the first two episodes of the Rock And Chips trilogy.
