Here We Go Again: "The Ed-Touchables", "Ed, Ed, And Away", "Luck of the Ed", and "Thick As An Ed" all end this way.
He Who Fights Monsters: Subtle suggestions are made throughout the show that Kevin's Jerkass behavior is a result of constant harassment from the Eds. In "See No Ed" he becomes increasingly suspicious after the Eds disappear for an extensive period time, to the point of becoming a paranoid wreck convinced of the Eds preparing to scam him at every turn. His point of view changes after witnessing Eddy's own Freudian Excuse in The Movie however.
Humongous Mecha: Double D has successfully built at least two of them—one in "One of Those Eds", and a T-Rex mecha in one of the flashback sequences in "The Good Ol' Ed".
Hyperspace Mallet: Rolf smacks Edd with the "Hat of Discipline", which is essentially a giant mallet-hat.
Edd: ...What is that, Rolf? Rolf: The Hat of Discipline. DO YOU LIVE IN A CAVE?!
Hypno Fool: In one episode, everyone but the Kanker Sisters and Jonny. Yes, even Plank.
Jonny came around to it eventually.
Hypocritical Humor: The first scene in "Know It All Ed", where the Eds find a box of turkey basters, er, Canadian squirt guns:
Eddy:(holding up a turkey baster) What we have here is a squirt gun. Edd: Please, a squirt gun? Eddy: What? Yeah! A Canadian squirt gun! Ed:Canadians are weird! Eddy: Watch and learn, boys. Just fill... Edd: Even if they were Canadian, Heaven forbid, I don't think they're... Eddy:(squirts Edd) And squirt! Canadian style!
The hypocrisy comes from the fact that this show was made by Canadians.
Antonucci, the creator of the show, is an Italian immigrant to Canada.
One episode focuses on Eddy trying to prevent Kevin from revealing his Embarrassing Middle Name (Skipper). After it's outed, Edd tries to comfort Eddy by saying that he has one too (Marion). As soon as he learns it, Eddy shouts it out for all the cul-de-sac to hear.
Jonny talks to a slab of wood, but is quick to call others crazy or weird.
Idea Bulb: "High-Heeled Eds". While trying to think up a way to scam Sarah, Nazz and Jimmy, Eddy gets one, though it flickers out briefly until he adjusts it.
Also in "It Came From Outer Ed". Ed gets an idea for a scam and holds up some turf over his head while saying, "Boing! It's a light bulb!"
Idiosyncratic Episode Naming: Every title is a play on a popular phrase, or the title of a related work, with "Ed" replacing at least one syllable.
Idiot Ball: Everyone's held it at least once, but Eddy's the one who usually holds it.
Impossible Leavening: In "An Ed Too Many", the Eds make pizza. Eddy ignores Edd's instructions for how much yeast to use for the dough, pouring in the entire container. The thing rises so much that Eddy's fist gets caught in the thing when he tries to punch it down. They have to have Ed belly-flop on the thing to press it down enough.
Improv: A surprisingly notable AVERSION of this for the series in whole. Despite the completely random lines that Ed and some of the other characters say throughout the series, every last one of them was written into the script first. Ed's voice actor, Matt Hill, once explained that Danny Antonucci did not allow the actors to improv or ad-lib even the smallest amount. This once lead to a recording session lasting FIFTY-SIX takes before Danny finally thought that the delivery was perfect to use for the episode.
In One Ear, Out The Other: Happens a few times. On one occasion Eddy sticks his hand clean through one of Ed's ears and out the other, and in another Eddy squirts a turkey baster at the kids the water passes through Sarah, Jimmy, and Johnny's ears.
Invisible Wall: In one episode, the Eds have built an office-like area with nothing but lines of tape indicating where walls would go. At one point Ed smacks right into one.
Irony: In "All Eds Are Off", when Ed Wins the bet and decided to spend the prize money on gravy.
Eddy:(angry) Oh come on! You're gonna spend the money on more gravy? Edd:(happy) Irony, Eddy. Look that up in the dictionary.
It Amused Me: The reason why Kevin popped the bubblegum bubble that Ed, Eddy, and Jonny were riding in at the time in "For Your Ed Only". He gets a minor comeuppance later on when the Eds tie him to a tree after he eavesdrops on them over Sarah's diary.
Eddy is this at times. He's greedy and arrogant, but he does have his moments where he shows he genuinely cares about his friends. He rarely shows his softer side but it's there ("Momma's Little Ed", "Jingle Jingle Jangle", "A Fistful of Ed"). He may have a Hidden Heart of Gold, if you think about it. He always tries to make money because he wants to buy the jawbreakers and share them with his friends, and that's why he scams. Also proven in 'Here's Mud In Your Ed', where he begins thinking of what he'll do when he becomes rich: the first thing he wants to do? Buy Edd a new hat, when you would expect greedy Eddy's first thoughts to be of his own self.
Likewise, Bratty Half-Pint Sarah may be a total jerk towards the Eds (And downright abusive/manipulative towards Ed), but she shows genuine kindness and concern over her friend Jimmy, she has a soft spot for Double D and, most of the time, she gets along well with Nazz. And deep down she does care about Ed, such as when, in one episode where the Eds were trapped in a "haunted" house and pretending to be attacked by ghosts, she squeals: "Somebody save my idiot brother!"
And Kevin seems to have been somewhat of a not-so-nice nice kid either. However he's good friends with Rolf, and will lend him a hand when needed. He also sticks up for the other kids if the Eds do something to them and, with three exceptions, he seems to be pretty generous with the mountain of jawbreakers in his garage— and it's worth noting that he was originally going to share some with the Eds before Eddy tried to pull his drawbridge scam on him. And in a couple of episodes, Kevin can be seen getting along with Double D (such as when Kevin strikes up a conversation with Double D while fixing his bike).
May Kanker is mostly seen being a local bully along with her sisters. But unlike them, she's implied to be a real sweetie deep down and has true feelings for Ed, not just a creepy obsession (it was evident in the Valentine's Day special). She's really more naive and dimwitted than evil.
Lee and Marie are this as well, though it rarely shows. As much as they like to pick on May, they still care about her. Such as when they capture Ed to apologize to May when they went too far with insulting her. And they are quite protective of her in the Valentine's Day episode (Marie: "Where's our May?!", Lee: "Tell your stupid friend to stay away from our sister!")
Kaiju: Ed's a small-scale one of these in "The Day The Ed Stood Still", with some Xenomorph for flavor. The Mis-Ed-Ventures game would later feature a level with Ed's monster "form" playing this straight.
Karma Houdini: The kids and the Kankers can do almost anything they wish to do and NEVER get punished for it. The Eds, meanwhile, have only gotten away a few times.
Edd gets a minor one in "Smile For the Ed" when Eddy gets a week's detention for impersonating the principal, which Edd actually did (though Edd was trying to help).
Eddy gets his only calling in "A Fistful of Ed". Despite the anguish he put Edd through, the only punishment he receives is Kevin taking his jacket. He doesn't even get his usual beating (like the one Jimmy gave to Edd in the episode).
Kick Me Prank: Eddy to Edd in "A Case of Ed", Kevin to Rolf in "Out with the Old, In with the Ed".
Kick the Dog: Eddy, Ed, Marie and Lee forcefully separating Edd and May, respectively, in the Valentine's special. While it's technically the right thing to do, it's hard to see such a happy pair split apart like that (neither of which done anything to each other).
Edd himself has a minor one in "Mission Ed Possible" when he willingly gave Eddy and Ed's report cards to their parents, not caring whether or not they would be subjected to physical or mental abuse afterwards. This is the guy who'd wipe Ed's drooling mouth and nurse Eddy whenever he gets hurt. He gets repercussion at the end by Kevin, as usual.
Kids Are Cruel: Everyone on the show has been known to treat each other like total crap. No one on the show is safe from teasing, bullying, getting beat up or even sexual harassment (which is always from the Kanker sisters).
This is taken to the nadir in "Out With the Old, In With the Ed" when Rolf chops down Edd's door with an axe, and the kids rob his school supply closet bare. What The Hell, Neighborhood?
Kidanova: Eddy tries, as does Kevin, who's only slightly more successful.
Leitmotif: Not a music example, but the makers seem to like giving Eddy the sound of someone shuffling across a basketball court when he's running.
Ed sounds like a horse galloping most of the time when he runs. When he's not sounding like a car with a faulty clutch. Actually, Ed makes a lot of horse sounds come to think of it...
Whenever Double D starts sweating, little farting sounds can be heard.
Sarah tends to get wildcat noises, especially when enraged.
For actual musical examples, the Eds get an excerpt of their theme song whenever they're up to one of their (well, Eddy's, really) schemes. Sarah usually gets a dainty piano jingle whenever she's on screen.
Left the Background Music On: Double D actually lampshades this in one episode, where the Eds open up a hula school, and he is lassoed into setting the mood by playing traditional hula music on his steel pedal guitar; once Sarah and Jimmy interrupt the lessons, he then switches the mood to sound more like the show's style of music scoring, that is until Eddy shouts at him, "Give it a break, will ya?!"
Misery Builds Character: After the Eds wrongfully accuse Jonny of being a "serial toucher" and sentence him to rolling down a hill in a giant tire, Eddy justifies it by citing the trope. Given his rather shocking history of abuse from his older brother he might justifiably believe it.
Misplaced Retribution: Frequently done by the cul-de-sac kids. No matter which of the Eds have wronged them, they are almost always punished as a group. Sarah excuses this at least once:
Sarah: Double D looked so innocent, but it's like they say, give 'em an inch, and they'll take a mile.
On the Halloween special, Ed goes around beating up people and EDD AND EDDY are beaten up instead and Ed goes unharmed, and in the episode "All Eds Are Off", Ed contaminates the pool with gravy and Eddy receives detention for it instead.
Missing Episode: Three "Special Ed", which was finished but never aired due to (depending on who you ask) being either too surreal or "too real" for television. Not much else is known about it other than the fact that it might of been A Day in the Limelight for Ed. The other two, "Luck Be an Ed Tonight" and "A Room and an Ed" may have never even left the planning stages.
Mouth Cam: In one of the episodes, they're filming a video, Ed randomly swallows the camera (shouting "Man the helms! DIVE, DIVE!"), ending up in a shot from inside his stomach as Edd digs it back out.
Nausea Fuel: In-Universe: when Ed gobbles all the food in the Cul-De-Sac, Eddy makes a scam of selling it back to the hungry neighbors: he roots around in Ed's stomach and yanks out the requested item. Edd is noticeably sick.
Never My Fault: Eddy does this for an episode when he upsets Rolf after throwing the Sea Cucumber Ball and more so when Rolf gets upset. Admittedly Eddy is often the first to say he never does anything wrong, and that it's outside forces doing it.
Noodle Incident: The plot of The Movie centers around this. It was evidently so horrifying, so far beyond what the Eds usually do, that the kids aren't looking for their money back, they want to kill them.
In one episode, where Rolf gives his cursed phone to Eddy, a runaway ice cream cart bursts into his room, bounces off a chair, bounces off the ceiling, and lands squarely on Eddy. The look on his face before contact can only be described as this.
Double D makes a sterling facial example in "Run For Your Ed", as seen here.◊
During the climax of 'If It Smells Like an Ed', the Eds share an expression best described as pure terror when they are faced with the Sadistic Choice between the Angry Mob of kids and the affections of the Kanker Sisters.
A recurring example is the Eds screaming in unison upon seeing or hearing the Kankers.
Omega Cast: Does this for its entire 5 seasons except for The Movie where we see Eddy's older brother.
Once per Episode: Every episode opens with one or more of the Eds doing something strange, or some sort of scam, that has almost nothing to do with the rest of the episode and only occasionally setting up a completely different plot.
One Steve Limit: As we can see in the episode title, this has been averted, leading to the next trope:
Oven Logic: In "Oath to an Ed", Eddy did this with a microwaveable burrito, five seconds after he'd already delegated the task to The Smart Guy. It ended up imploding on them. No burrito merit badge for them.
Ow, My Body Part!: Lampshaded in one episode where the Eds stage a plane crash in Kevin's yard, claiming it was the result of Ed's attempts at sky-writing.
Eddy: Ed was flying, sky-writing... when... he ran out of syllables!
Ed: (Double D pulling him from the "wreckage") Ow, my liver! Ow, my lasagna!
Double D: (Softly) Ed, lasagna isn't a major organ.
Ed: It isn't?
Eddy: He flew into reverse... to erase a... spelling mistake... then crashed into your yard! It was hedious! If only he had landed on his head!
Ed: (Being dragged by Double D) Ow, my finger nails! Ow, my skin! Ow... hi, Kevin!
Panty Shot: Nazz in "Boom Boom, Out Goes The Ed" and "A Town Called Ed."
Piano Drop: To get to the candy store, Eddy takes a shortcut through Jimmy's yard and runs under a ladder. Jimmy's "garden in the sky' then falls but misses Eddy. Eddy then starts to run, only to have a piano fall on him.
Kevin: That's for gobbling all over my bike, dork!
Pink Girl, Blue Boy: Sarah and Jimmy. Sarah wears a pink tank top while Jimmy wears a blue shirt.
Present Peeking: In "Jingle Jangle Eds", Eddy finds his Christmas presents and peeks inside, only to be severely disappointed. ("A dickie? They still make those?") He then goes house to house trying to get some of the other kid's presents instead.
