"Ed, Edd n Eddy's Boo Haw Haw" is the third special of Ed, Edd n Eddy, first aired in 2005.
The Eds try to find the town of "Spook-E-Ville" using an old map from Eddy's Older Brother, but on the way Ed has hallucinations of the kids being horrific monsters.
- Acid Reflux Nightmare: Spending excessive hours watching horror movies caused Ed to lose what grip on reality he had.
- Actually Pretty Funny: Eddy actually found the beatdowns Ed gave the kids amusing...until they came back to wallop him.
- All for Nothing: The main plot of the episode involves the Eds following a map Eddy received from his brother to a town called Spook-E-Ville, where they will get tons of candy at every house. They follow all the clues, with Ed beating up all the kids along the way due to his imagination, and eventually arrive at Spook-E-Ville. Eddy and Double D quickly find out though that Spook-E-Ville is not real and they just went in a huge circle that led them back to the Cul-de-Sac. Not only did they waste a good portion of their Halloween night with this pointless quest, Ed angered all the kids into attacking him and his friends and the Eds don't get to do any trick or treating at all.
- Animation Bump: Some of the show's most detailed scenes of animation are in here, such as Ed's flashes of the nightmare version of the Cul-de-Sac.
- Ax-Crazy: Ed arguably goes from a harmless Cloudcuckoolander to this in this special.
- Big Brother Bully: The episode is another emphasis on how Eddy's brother is a jerk to Eddy - the map he gave him only lead the Eds back to the Cul-de-Sac and there was no Spook-E-Ville. As Double-D put it, he tricked rather than treated Eddy.
- Crouching Moron, Hidden Badass: Ed.
- Downer Ending: The episode ends with Edd and Eddy getting beaten up for Ed's actions. Nothing goes right for the trio, except for Ed.
- Egging: This is what Kevin does to the Eds. While fighting the Headless Horseman in his imagination, Ed returns fire at Kevin.
- Failed a Spot Check: After arriving in what he thinks is "Spook-E-Ville", Eddy doesn't recognize it as the Cul-de-Sac at first. He even knocks on the door of his own house before Double-D makes him realize it.
- Five-Second Foreshadowing: It was hinted a moment before the Eds arrived in what they thought was Spook-E-Ville that something was a miss as they passed a shovel that somebody (possibly Eddy's Brother) had left in the middle of nowhere.
- Fun with Homophones: While battling the "vampiress", Ed claims "A stake with defeat you!", while pulling a steak out of his pants before slapping it against her and burying her. Afterwards, Eddy asked Ed if he had anymore of those steaks.
- G-Rated Drug: The whole special is basically a metaphor for a psychedelic trip, only much creepier. This is all due to Ed's habit of watching too many monster movies, which cause him to hallucinate and see all the cul-de-sac kids as various macabre figures.
- Gorgeous Gorgon: Played with regarding Nazz—her costume is of a really cute version of Medusa (Double D gives her props for going for a classical mythology monster rather than a pop culture one), but Ed's hallucination of her as an actual gorgon leads him to envision her as a thoroughly horrifying and grotesque monstrosity.
- Horny Viking: Ed as Lothar.
- Idiot Houdini: At the end, Ed was completely unaware of all the troubles he's caused to his friends and the kids.
- Impact Silhouette: After Ed attacks Jimmy with a stop sign, he still has it in his hand, and you can see Jimmy's silhouette.Eddy: Hey, a demented stop sign! That's the first clue to Spook-E-Ville! We're on the right track!
Double D: The sign that Ed dented?
- Jerkass Has a Point: Sarah confronting the Eds and demanding they return Jimmy's candy. Even her resorting to violence is excusable since Ed beat the hell out of Jimmy without provocation.
- Karma Houdini: Easily one of the most shining examples of this trope in the entire show.
- Kick the Son of a Bitch: Kevin was the only one who actually warranted the beat-down Ed gave him. Downplayed with Sarah, who had a good reason to attack Ed (see Jerkass Has a Point).
- Misplaced Retribution: Even by this show's rules. The vengeful kids beat up Double-D and Eddy for something that was COMPLETELY Ed's doing! Meanwhile, they don't even lay a finger on Ed! See Karma Houdini above.
- Monster Mash: Ed sees the kids as monsters from different genres:
- Never My Fault: While most of the kids were innocent victims who'd done nothing to warrant Ed's wrath, Kevin is not among them—he genuinely attacked the Eds For the Evulz, thus he got what was coming to him when Ed's imagination kicked into high gear. Yet, during the climax, he has the nerve to see himself as the victim.
- No-Holds-Barred Beatdown: The entire special.
- Not Evil, Just Misunderstood: Jonny as the Giant Spider, at least according to Ed. While Ed uses violence against all the other monsters (except the Kankers, who terrified him too much), he opts instead to appease Jonny with an offering of candy, which works like a charm.
- Only Sane Man: Double-D was the only one concerned about Ed's out of control behavior, while Eddy kept shrugging off what he was trying to tell him and was only focused on finding Spook-E-Ville.Double D: (To himself) Why do you even bother? No one listens. What do they care?
- Pre Ass Kicking One Liner: "EARTH IS NOT YOUR SALAD BAR!!" "Be gentle!"
- Shown Their Work: In-universe. Double-D compliments Nazz (who's dressed as Medusa) on dressing up as a classical monster as opposed to a pop culture one.
- Through the Eyes of Madness: After watching so many B-Grade Monster movies, Ed starts to see everyone around him (except for Edd and Eddy) as monsters, and at the end of the special, sees his friends happily playing together when they're actually being beaten up by the kids. We actually get to see those hallucinations firsthand.
- Treasure Map: Eddy's Brother gives Eddy one that supposedly leads to a candy rich town called Spook-E-Ville. However, it's revealed to be a Fool's Map as it only leads the Eds in a circle back to the Cul-de-Sac. You'd think Eddy would've learned considered what happened the last time he followed one of his brother's maps.
- Windmill Crusader: Ed makes Don Quixote look completely sane by comparison.
- Would Hit a Girl: While Ed normally isn't allowed to do it, he probably makes an exception when it comes to female "villains" (his hallucinations of Sarah and Nazz).
- Wrong Genre Savvy: Ed, to the extreme.
