"X Marks the Ed" is the 11th episode of Season 3 and the 63rd episode of Ed, Edd n Eddy. In this episode, Eddy gets a huge pimple and is aided by Rolf, who tries to help make it disappear while at the same time trying to not let others see it.
The Eds, looking for some easy money, decide to catch some fish from Ed's backyard pool to sell, only to find themselves with absolutely no success. Despite Edd's skepticism that they'll actually find anything, Ed claims he got a bite and, upon pulling his Fishing Pole, The Eds find a fish-like creature constructed from various foodstuffs (Ed's Freezer Experiment from the Season 2 Episode, "Rambling Ed") at the end of the fishing rod. Ed, clearly happy to see it again, thrashes it back into the water, causing a wave that sends them flying into a bush. Eddy, after recoiling, immediately pounces on Ed to reprimand him about ruining scams, but Ed seems to be distracted by something else. After being asked by Eddy as to what he's looking at, Ed takes Eddy to the pond to see his reflection, revealing a red lump on top of his head. Upon an observation by Edd, Edd reveals it's nothing more than a pimple and that he should be proud of it, as he's now reaching adulthood. However, Eddy, embarrassed, wishes to hide it. Ed tries to help Eddy by rubbing it off (without any success). Edd tells Eddy to stop worrying; however, Eddy decides to hide when Ed calls for Jonny and Plank. Despite hiding the bush, Ed finds Eddy and showcases it to Jonny. Eddy, after facing some rather insulting jokes, suddenly disappears.
Eddy, desperate to conceal his problem, tries to use his dad's wig to conceal his problem, only for it to be attacked by Ed. Edd then tries to help Eddy by trying to conceal the "zit" with some foundation, only for the pimple to grow bigger. Eddy turns back to tell Edd he'd made it bigger only to find that Jonny had been charging the kids 25 cents to see his zit. After a round of humiliation (which made his pimple grow considerably) by The Kids and Ed, Edd angrily tells them to leave the house, disgusted by their antics over Eddy's pimple. Ed then sadly leaves, but Edd tells him that he doesn't have to leave, which causes him to happily come back. Rolf, sympathizing for poor Eddy, tells The Eds to stop by Rolf's House in 1 hour to get rid of the zit. Eddy, albeit frightened, agrees.
The Eds try to get Eddy across the street to Rolf's house, unnoticed, but The Kids suddenly appear and begin to take photos of Eddy's pimples, and are chased to Rolf's House. Luckily for The Eds, Rolf manages to drive them away. Rolf begins making Carbuncle of the Flesh Stew, a remedy he'd learned about in The Old Country that is handed down through many pimply-faced elders. He gets Eddy to marinate in a barrel full of lard and Edd and Ed to help him prepare the broth, which includes softening a squid and grating a turnip. Rolf then adds the Pickled Towel of Mith and states that the simmering of the towel takes 14 days and 14 nights to prepare, which shocks Eddy. Rolf then exclaims that he'd thought ahead and pre-made one in advance. He then takes a towel out of the broth and places it on Eddy head. After a few seconds, he then kicks Eddy out of his back door. Rolf then places a crate on his head and then places a chicken in the crate, claiming they must be quick. The said chicken then starts pecking down on the pimple continuously. Ed states to Edd he really wants a chicken peck on the head, but Rolf tells Ed and Eddy to pick Eddy up in 24 hours, which Rolf spends carving a wooden shoe.
After 24 hours, Ed and Eddy return to pick him up. Rolf pulls Eddy out of a Giant Tomato and shows Eddy his face, revealing that his pimple is gone, but his head has been shrunk considerably and he had a higher pitch voice. Eddy, outraged, demands for Rolf to fix his head while Edd, intrigued, asks for an explanation as to how he did it, while Ed asks Rolf to shrink his head, too. The episode ends with The Eds chasing Rolf around his backyard to get him to shrink Ed's head, to fix Eddy's and to provide Edd with an explanation.
Ed: "Oh, I make a game out of mine, 'cause I'm productive. You can play connect-the-dots." [rolls up shirt revealing his back with a zit-connected boat] "See? It's a boat."
Ed: "I wish I had a zit." Edd: "Ed, you have a boat on your back."
Jonny: "You look like a lighthouse, Eddy!" Ed: "Haha! Or even a one-humped camel, huh Jonny?" Jonny: "Plank says, 'Eddy should join a circus!'"
Sarah: [about Eddy's zit] "I think I saw it move!" Kevin: "This is where I'm gonna bust a gut!"
Ed: "Fish! Fish!" Eddy: [excited] "It's mine! Reel it in, Ed!" Ed: "It's a fighter, Eddy!" Edd: [in disbelief] "Oh, please. No creature could survive in this pond!" Ed: "If it's not of this world it's mine!" [Ed pulls up a what looks like a giant fish made out of huge pieces of meat.] Edd and Eddy: "WHAT IS THAT?!?!?" Ed: [excited] "Oh goodie goodie! It's my freezer experiment! I wondered where Sarah hid it. Well, that's a keeper!" Edd and Eddy: "NO, ED! [The splash from the meat fish sends the Eds flying out of their boat.] Ed: "Who brought the tartar sauce?"
Eddy: "Oh, hey guys. Dad's rug really does the trick, huh?" Ed: (freaked out) "Attack the wig!" [Ed grabs the wig with his mouth and shakes his head like a dog] Edd: (shocked) "Ed! You're violating a hairpiece!" Ed: (in explanation) "Wigs scare me, Double D."
Eddy: [sourly while Edd treats his zit] "I feel like a sissy."
Ed: [planting a plunger on the zit] "I claim this planet in the name of Ed, bringer of bacon!"
Eddy: [talking in high-pitched voice with his head shrunk] "WHAT HAPPENED TO MY HEAD?!" Ed: (amazed) "It is so puny!" Edd: (similarly amazed) "This is worthy of a Nobel Prize!" Eddy: [angered at Rolf for shrinking his head] "WHAT'D YA DO TO ME, YA QUACK?!" Rolf: (confused) "Quack? I am Rolf." Eddy: "YOU'RE A QUACK! QUACK QUACK QUACK!!!" Rolf: "I am not a duck! I am Rolf! Edd: "How did you know what ingredients would react in such a way as to come to this conclusion?" Rolf: [not clear of what Edd said] "What?" Ed: "My turn for shrinkage, Rolf!" Eddy: [infuriated] "Fix me!!" Edd: [intrigued] "Tell me!" Ed: [excited] "Shrink me!!!" Rolf: [panicked] "Eh, stay back!" [runs away]
Rolf: "Away with you, protuberance of the flesh!" [kicks the barrel with Eddy covering his pimple with the pickled towel of Mirth out]
Kevin: "There goes the 'Ugly Dorkling'!" [everybody excepts Edd and Rolf laughs] Edd: [angered] "Are we just about done?!" [forces everyone out the door] "Please leave in an orderly manner! In all my years, I have never seen such deplorable behavior over one's elevation of the skin!" Kevin: "Man, Eddy's got a real honker, huh, Double-Dweeb?" [Ed follows the others out the door.] Ed: [sadly] "Too-tah-loo, Double D." Edd: [exasperated] "Not you, Ed!"
Rolf: "Rolf has great sympathy for the two headed ogre!"
When the Eds were "fishing," Eddy wasn't wearing any shoes, but when Ed shows Eddy his zit at the pond, Eddy's shoes are on even though he was not shown putting them on.
When Ed shows Eddy his zit, being a reflection in the water, his stripe should be on the other side.
Before Eddy looks into the bathroom mirror, Ed applies a toilet plunger to his bib-covered head. However, once Eddy's reflection is shown in the mirror, the bib has all of a sudden vanished, but the toilet plunger stays. If Eddy were to have taken off the bib, the plunger would have gone with it.
When Ed and Edd came to pick up Eddy, his head was driven inside a giant tomato, even though as Rolf waits for the 24 hours, he wasn't seen doing so.
When Rolf gives Eddy a mirror to show him that his head no longer has the zit, his head was not red. In the next scene, however, it was.
It is shown in this episode that Ed has a fear of wigs. On the contrary, he wore one in "Quick Shot Ed" and "A Boy and His Ed," yet he showed no signs of fear. It is possible that his fear developed between the latter episode and this episode.
In "Quick Shot Ed," Ed's wig was a ginger/orange color. However, in "Over Your Ed," his hair was shown to actually be that color naturally.
This is one of the only episodes where Jonny makes a scam.
If you listen closely in the scene where Eddy was getting pictures taken by the kids, you can hear several quotes from past episodes.
Eddy says, "I'm a minor, stop!" which is from the episode "Once Upon an Ed."
Edd says, "You all need help!" which is from the episode "Dim Lit Ed."
If Rolf had applied the "Pickled Towel of Mirth" only to Eddy's pimple and not his head, we may have seen different results.
The Mis-Edventures mission, "Must be Something I Ed," is similar to this episode. The mission involves Eddy having an allergic reaction from eating a footpowder-flavored jawbreaker that makes his face look sickly green, along with the kids taking snapshots of him in his hideous appearance at the end of the mission.
