- Actor Allusion: It's no coincidence that Daphne's Xenafication in the live-action film comes along when she's being played by Buffy. Also, her line, "This must be the secret relic thingy they worship," could be considered Buffy Speak.
- In an episode of What's New, Scooby-Doo?, when Daphne meets someone hired to impersonate her, she complains she is being played by an extra and asks whether Sarah Michelle Gellar was busy.
- In a different episode of What's New, Scooby-Doo?, Shaggy (played by Casey Kasem) happens upon an abandoned radio house atop a mountain. He asks Scooby if he'd like to hear his "DJ impression". When Scooby says yes, Shaggy clears his throat and does an "impersonation" of... Casey Kasem.
- One episode of Mystery Incorporated involved Shaggy and Scooby having dinner with Vincent Van Ghoul (an obvious Ink-Suit Actor expy of Vincent Price, who had played him in The 13 Ghosts of Scooby-Doo but passed away not long after). Several of Van Ghoul's quirks seen in the episode were ones Price was known to have, including a love of gourmet cooking.
- Adored by the Network: Some iteration of Scooby-Doo used to air on Cartoon Network every day. In recent years the selection has been limited and now on the main channel it's mostly just an occasional movie.
- Ascended Fanon: It was a common joke that in the original series Daphne and Fred were somewhere having sex, though in the actual series there was really nothing to imply that any of the gang were anything but platonic. It wasn't until years later that Daphne and Fred became Implied Love Interests, and then eventually just straight-up love interests.
- Beam Me Up, Scotty!: Velma is notorious for always losing her glasses. In the original episodes she only dropped them twice. The same goes for Daphne getting kidnapped, it really didn't occur that often enough to be her recurring character trait in the original series.
- Actually, Velma had her glasses knocked off her face once by Scooby, the other time after bumping her head. A third time, a bat plucked her glasses off and dropped them on Scooby's head, and a fourth instance had her glasses swept off her face from an errant bumper cart. And later, in "That's Snow Ghost", Scooby uses Velma's glasses to see the bundle of dynamite pursuing them on the log behind.
- Velma losing her glasses became a running joke based on her voice artist, Nicole Jaffe, whose glasses fell during a script reading for "What a Night for a Knight", and she was quoted as saying, "I can't see without them."
- Lampshaded in the Johnny Bravo crossover episode "Bravo Dooby Doo" after Velma and Johnny both grope for their displaced eyewear:
Velma: My glasses! I can't see without my glasses!Johnny: My glasses! I can't be seen without my glasses!
- "Old Man Jenkins" has become the term for the everyman Scooby-Doo villain. While there was a suspicious old man named Mr. Jenkins in one episode of the original series, but he turned out to be innocent.
- The Cast Showoff: The gang themselves, but most notably Velma in the movie Scooby-Doo and the Legend of the Vampire where they pose as contestants in the rock show contest (as The Meddling Kids) and eventually win by default. Velma sings the "Scooby-Doo, Where Are You!" theme. Poor child was petrified at first, but as she started singing, she put on quite a show.
- All five members of the gang and some of the other characters sing throughout the 2012 made-for-video feature Scooby-Doo: Music of the Vampire.
- Channel Hop: From CBS to ABC in 1976. NBC may even count, as Dynomutt, Dog Wonder was paired up with Godzilla for an hour-long show in 1981 on that network and the Scooby gang's appearances in Dynomutt were subsequently aired.
- Creator Backlash: Joe Ruby and Ken Spears didn't like Scooby-Doo! Mystery Incorporated, feeling that it missed the point of the characters and was too cynical. Some other writers seem to agree, as a few of the Direct-to-DVD have at least one joke at the series expense. Although the design work in some cases does borrow from MI's art style.
- Cross-Dressing Voices: Susan Blu as Flim-Flam.
- The Danza: Vincent van Ghoul was voiced by Vincent Price.
- In the live-action film, Fred is portrayed by Freddie Prinze, Jr.
- Defictionalization: You'd be surprised how many people have named their dogs Scrappy-Doo.
- Deleted Scenes: Like the stupid Scooby using "Scooby logic" (whatever that is) to die.
Scooby-Doo: [pretends to have a heart attack]Mondavarious: Stop it, Scooby. It didn't work the first 33 times you did it.Scooby-Doo: I'm dead, I tell you!Mondavarious: Then why are you talking?Scooby-Doo: [Face Palm] Rupid!
NASA member: "When did you feel these feelings of... self-despair?"NASA guy: "Oh, and Daphne! That chick is SO HOT!"NASA member: "And that giant Great Dane."NASA member: "I don't remember a 'Thelma'."
- Fred, Velma and Daphne have flashbacks. Well, originally. Fred wrote a book named "Fred on Fred: The Many Faces of Me", which was a really bad seller. Velma was working at NASA.
Daphne: [gets stuck in a tree] My butt! Is stuck! In a tree!
- All quotes from NASA... And Daphne learned karate... well, kind of.
Karate teacher: Dude, that chick is hopeless!
Velma: I'm just getting my groove on!
- Also, Velma and some other girls dancing... in their underwear! Brainwashed, though. So It Makes Sense in Context.
She knows that Bloody Scars are not alcoholic, doesn't she?
- And the deleted animated opening, and Velma's song; when Mondavarious says that:
- And finally a scene where Daphne's soul is extracted from her body and a demon possesses her.
- Dyeing for Your Art: For the live action film, blond Sarah Michelle Gellar note dyed her hair red to become Daphne. Additionally, brunet Freddie Prinze Jr. bleached his hair blond to play Fred. Also, redhead Isla Fisher became a blonde to play Mary Jane.
- Edited for Syndication: Footage from Act II of the very first episode, "What a Night for a Knight", is missing. It's where the gang is outside the museum as Fred is unable to open the rear door. He gets a ladder out of the Mystery Machine (which must be dimensionally transcendental to hold a ladder) and volunteers Shaggy to climb up and go in through a window high above.
Shaggy: Why me?Fred: Because that's a small window and you're the thinnest.
- In the first season of The New Scooby-Doo Movies, scenes running roughly a minute and a half were made but not used until season 2. The scenes never showed up in syndication, CN/Boomerang airings or DVD releases. Among the scenes were Jonathan Winters flipping a coin with Shaggy to see who would go up to the grist mill window ("The Frickert Fracas"), and Scooby trying to get the kids' attention to tell them he found a secret passage out of Moody Manor ("Guess Who's Knott Coming to Dinner").
- In the 1970-71 season, a minute of footage from season 1 episodes of Scooby-Doo, Where Are You! were cut to make room for CBS's "In the Know" interstitials. ("In the Know" were 2½-minute educational capsules hosted by Josie and the Pussycats. It would be replaced the next season with CBS's long-running interstitial series In the News.)
- Hey, It's That Sound!: "Where Are You!" episode "Spooky Space Kook". The UFO used the "electronic rattlesnake" noise from the Heat Ray warming up from the The War Of The Worlds 1953 film.
- Name's the Same: "Roller Ghoster Ride", the unused Either/Or Title of the Pup episode "Terror, Thy Name Is Zombo", is also the title of a What's New episode. "Wrestle Maniacs" is also a title of an episode of both series.
- Old Shame: Freddie Prinze Jr. (Fred) and Sarah Michelle Gellar (Daphne) don't think very fondly about the live action film. Among other things, Prinze hated wearing the trademark ascot, and Gellar hated wearing Daphne's trademark Go-go boots. Prinze also had to shave his head after filming because the blond dye ruined his hair.
- The Other Darrin: Considering this is a franchise that's been around for more than 40 years at this point, it's understandable that most characters have had many voice actors. The only cast member to stay consistent throughout the whole series is Fred (since 1969, the only time Frank Welker hasn't played Fred was in A Pup Named Scooby-Doo).
Scooby: Don Messick (1969-94), Hadley Kay (1997), Scott Innes (1998-2001), Frank Welker (2002-present)Shaggy: Casey Kasem (1969-97, 2002-09), Billy West (1998), Scott Innes (1999-2001), Matthew Lillard (2010-present), Scott Menville (Shaggy and Scooby-Doo Get a Clue!)Fred: Frank Welker (1969-present), Carl Stevens ("A Pup Named Scooby-Doo")Velma: Nicole Jaffe (1969-74, 2002-03 DTV films), Patricia Stevens (1976-79), Marla Frumkin (1979-80, 1984), BJ Ward (1997-01), Mindy Cohn (2002-present), Christina Lange (A Pup Named Scooby-Doo), Kate Micucci (Be Cool, Scooby-Doo!)Daphne: Indira Stefanianna Christopherson (1969), Heather North (1970-85, 1997, 2002-03 DTV films), Mary Kay Bergman (1998-2000), Grey DeLisle (2001-present), Kellie Martin (A Pup Named Scooby-Doo)
- The full complement of voice actors throughout the Scooby-Doo animated timeline:
- Mostly averted in Brazil, with only Fred not having his original actor as of What's New…, basically the inverse of English. While the other teens' actors are now in their 70s (Scooby's in his 90s), Fred's new voice actor is in his early 30s, and he sounds believably like a teenager.
- Recycled Script: Monsters Unleashed is accused of this.
- Major similarities to the Buffy the Vampire Slayer season two episode "Halloween":
- Sarah Michelle Gellar's character giving her nerdy best friend a makeover to attract the guy she wants, but ends up attracting Seth Green's character instead.
- Monster costumes becoming real monsters. (Although this one had been a Scooby fan idea decades before there ever was a Buffy)
- Referenced by...: When Wayne's World did a spoof of Multiple Endings, one of them was "The Scooby-Doo Ending".
- Romance on the Set: Daphne's and Fred's actors in the movie were, of course, a real-life item.
- Screwed by the Network: When CBS brought Where Are You! back in 1974 after a two-year hiatus, Hanna-Barbera wanted to make new episodes. But CBS felt they could get just as much mileage, if not more, from repeats. CBS would cancel Scooby on August 7, 1976, a full month before the new season began. A week later, Scooby (which moved to ABC a month later) was replaced on CBS with Clue Club.
- Talking to Himself:
- Scooby with Scrappy after Don Messick took over Scrappy's voice from Lennie Weinrib.
- From Witch's Ghost to Cyber Chase he and Shaggy were both voiced by Scott Innes. Since Scooby and Shaggy share most scenes, that's quite an accomplishment.
- Since 2002, Frank Welker has been the voice of Fred and Scooby.
- The Abridged Series: Scooby Doo Abridged, which is based off the first cartoon Scooby-Doo, Where Are You!!
- Wag the Director: Casey Kasem stopped voicing Shaggy in 1997 after having to voice the character in a Burger King commercial, since Kasem was a devout vegetarian. He returned to voicing Shaggy in 2002 under the condition that Shaggy became a vegetarian like Casem himself. Now that Kasem is gone, Shaggy has gone back to his old ways.
- What Could Have Been: Hanna and Barbera reflected in a later interview that the show was originally just going to be about "a group of teenagers solving crimes", but "we threw in a dog, and he turned out to be the star of the show".
- The dog was originally a sheepdog named Too Much, but The Archie Show (which was also on CBS) already had Hot Dog, Jughead's pet sheepdog. An H-B staffer raised Great Danes as a hobby, so they made the dog a Great Dane. It was Fred Silverman and (indirectly) Frank Sinatra who gave the dog the name Scooby-Doo.
- In its developmental stage as "Mysteries Five", there were originally five kids who, in a knockoff of The Archie Show, played rock music as well as solved mysteries. Their names were Geoff, Mike, Kelly, Linda, and W.W. (as well as their bongo-playing sheepdog, Too Much). Geoff and Mike were melded to become Fred (originally Ronnie but renamed after CBS programming head Fred Silverman), Kelly became Daphne, Linda became Velma and W.W. became Shaggy.
- In the original pitch, Velma and Shaggy were siblings. It showed in the debut episode, "What a Night for a Knight", as Velma has Shaggy's cough medicine at hand, and in "Decoy for a Dognapper", Shaggy keeps a spare pair of glasses for Velma.
- The first live-action film was originally intended to be aimed at an older audience, including nudity and sexual/drug-related humour. Some of the early trailers included this material, which was cut when the studio decided to aim for a G rating.
- The Wiki Rule: Scoobypedia
Trope Namer for:
- Let's Split Up, Gang
- Scooby-Dooby Doors: It may be one of the most frequently referenced sequences in any Hanna-Barbera/Warner Animation production, if not all of western animation. Yes, that's right, Scooby-Doo is the Western equivalent of Neon Genesis Evangelion.
- The gag had been used in Looney Tunes shorts long before that. One of the oldest uses was in a live-action silent comedy made in the early 1920s. Amusingly, it took place in a haunted mansion, and the ghost was revealed to be a fake.
- Scooby-Doo Hoax
- Scooby Stack
- Shaggy Search Technique: Shaggy would often uncover secret passages by sheer accident.
- The Scrappy
- You Meddling Kids
