Scooby-Doo, Where Are You! is a popular animated television series created by Hanna-Barbera, launched all the way back in 1969. It consisted of two seasons which originally aired Saturday mornings on CBS. The series spawned the famous Scooby-Doo franchise, which is still running to this day, lasting over forty years!Scooby-Doo, Where Are You! featured a gang of four mystery-solving teenagers, and their talking Great Dane, Scooby-Doo. In each episode, the Scooby Doo Gang runs into some sort of paranormal activity, and it's up to them to solve the case. In nearly every episode, however, it just turns out to be a man in a mask, though the gang never seems to catch onto this.
Scooby-Doo, Where Are You! provides examples of the following Tropes:
'70s Hair: The characters were designed in 1969, but close enough.
Black Belt in Origami: In "Mystery Mask Mix-up", Shaggy tries to bluff the ghost: "Go on, I dare you to cross the line, but I warn you, I know judo, chop suey, and Chinese checkers!" The ghost (being Chinese) was not intimidated.
In "Don't Fool with a Phantom", the last episode of the original Scooby-Doo series, the Wax Phantom (the Monster of the Week) left Shaggy and Scooby tied up on a conveyor belt that would dump them into a tank of melted wax, and Shaggy quipped, "That bit went out with the silent movies!" You know it's a Dead Horse Trope when it's being parodied in the early 1970s.
Not that this stopped the Snow Ghost from tying Velma to a log and sending it towards a buzzsaw in "That's Snow Ghost"...
The Dog Bites Back: at the end of "Decoy for a Dognapper", the kidnapped dogs chase and tree the villain.
The Dog Was the Mastermind: Done in "A Clue For Scooby Doo". The villain is disguised as the alleged ghost of a dead sailor. The episode presents two suspects: the dead sailor's wife, and another sailor. The villain turns out to be the dead sailor, who was not so dead after all. (However, his wife was an accomplice.)
Velma: When the barometric pressure dropped and the warm offshore air came in contact with the midland cold front, we ran into some unnavigable nucleation.
Fred: You're right, Velma — whatever you said.
Velma: I said, we're lost in a fog.
Fine, You Can Just Wait Here Alone: In "Spooky Space Kook", Shaggy and Scooby declare they aren't going any farther. Fred responds, "Fine, if you want to stay here — alone." A ghostly laugh sends the two running to catch up.
Hero Stole My Bike: in "Decoy for a Dognapper", Shaggy asks a friend if he has anything for him to follow Scooby's abductors. When the friend says, "Only my motorbike", Shaggy roars away with it. At least he asked...
In this series, it was strongly implied that Fred and Daphne were boyfriend-and-girlfriend, such as dancing together at parties and whatnot, but it was never confirmed if they were an Official Couple.
The same could be said for Velma and Shaggy. As well as being designated dance partners, he carries her spare glasses on him at all times and she brings his cough medicine when he's ill. Not to mention how they dressed up as Tarzan and Jane, as well as Mark Anthony and Cleopatra.
Imprinting: Scooby has a baby chick do this in one episode. When he returns it, a whole nest of eggs hatch and all of them imprint on Scooby.
The Ketchup Test: Fred pulls this off in "What a Night for a Knight", in order to confirm that the 'blood' on the museum floor wasn't blood. It was paint.
Knew It All Along: In "Never Ape an Ape Man", Shaggy gets "grabbed" by a stuffed ape. When Velma tells him it's not real, he answers, "Well, I hope you don't think he had me fooled for a minute. I knew it all the time."
Not Now, We're Too Busy Crying Over You: In the episode "Scooby-Doo and a Mummy, Too", Shaggy did this over a stone statue of Scooby: "He was like a brother to me! (the real Scooby approaches him) Look, Scoob, you've been turned to stone!"
Shaggy: Yeah. But now I know how a baseball feels when it gets knocked out of the park.
Ominous Fog: Becomes a plot point in "Go Away Ghost Ship".
Only Known by Their Nickname: Fans didn't learn that Shaggy's first name was Norville until years later ([[spoiler:he has a younger named Maggie in later series, but her nickname is "Sugie").
Our Ghosts Are Different: For starters, they're all just people in costumes, but that's not to say the villains didn't get creative. Examples range from a floating white sheet to glowing blue alien with a skull head, and even a "ghost" who could actually walk through walls (by using a mirror-projected image of himself).
Painted Tunnel, Real Train: During the chase sequence in "Don't Fool With a Phantom", Shaggy and Scooby paint a fake door on the wall before fleeing the room in another direction. When the Wax Phantom catches up to where they had been he opens the fake door...and promptly crashes into (and through) the very real brick wall behind it.
Panty Shot: Velma in "Decoy For A Dognapper." She and Shaggy flail their arms and legs warding off a flock of bats; Velma kicks her skirt up high enough to show panties the same color as her skirt.
Pintsized Powerhouse: Velma. She's the shortest but can lift all the other members of the group at once.
The Summation: Every time the monster is revealed to be fake, the gang explains why the masked man went through all the trouble he did, how he did it and how the gang managed to piece the clues together.
Taken for Granite: The gang learns that the mummy of Anka turns anybody to stone that disturbs his resting place. The mummy (presumably) turns a professor and a doctor and Scooby to stone, but the gang soon learns that they were cast duplicates made of concrete.
Toon Physics: Applied several times, sometimes characters (usually Shaggy and Scooby) could do things like hang from ceilings by jackhammers or leave things suspended in midair.
The Walls Are Closing In: In "A Night of Fright is No Delight", the gang gets trapped between the encroaching walls of the room they're in. Only Scooby "playing" the piano saved them.
Wax Museum Morgue: The last episode of the series "Don't Fool With a Phantom" takes place in one, although given that this is Scooby-Doo there are no actual dead bodies.
Witch Doctor: Two prominent examples as both are featured in the theme songs of their respective seasons. Firstly, the Navajo inspired witch doctor from "Decoy for a Dognapper" and the Hawaiian inspired one from "A Tiki Scare is No Fair" with the latter being a more iconic example.
Wolfman: In the episode "Who's Afraid of the Big Bad Werewolf?". One also makes an appearance in "A Gaggle of Galloping Ghosts".
Worthless Treasure Twist: in "A Night of Fright is No Delight", Scooby alone of all the potential heirs manages to stay the night in the "haunted" castle. Unfortunately, the million dollars that are legally his are all Confederate.
You Just Had to Say It: Of the "original speaker" variant, in "Who's Afraid of the Big Bad Werewolf?" Shaggy comments, "I wish I knew how Mr. Hairy fits into all this." When Fred answers that they'll figure it out, Shaggy groans, "Oh, why don't I just keep quiet?"
