"Cleanliness Is Next to Edness" is the 4th episode of Season 5 and the 106th episode of Ed, Edd n Eddy. In this episode, Edd finds out that his shower is out of order, so he tries to find another shower to use in order to start off his day. However his mind slowly begins to deteriorate as he gets more dirty in his long search for a shower to use.
Edd is peacefully sleeping when Ed's shoe flies through his window and ricochets about the room before smacking him in the head, waking him up. Edd then hears Eddy calling, saying that they're late for school. Edd gets up and calmly tells his friends that it's Saturday, and therefore there is no school. When Eddy realizes this, he berates Ed for waking him up on a weekend. Ed apologizes by claiming that his belly told him it was Bottomless Gravy Day in the cafeteria at school. But Eddy, still mad, chases him around for waking him up early for nothing.
Edd, fully awake now, decides to start his day. He gathers his supplies and gets ready for the heaven that is his shower. However, when he opens the bathroom door, he finds that it has been totally demolished, and reads a sticky note from his parents telling him that the bathroom is being remodeled.
At Eddy's house, Ed is pestering Eddy, trying to get Eddy to forgive him. Eddy, to quiet Ed down, tapes a magazine to his window and gets into bed. He is about to fall asleep when Edd appears, asking to use Eddy's shower. Eddy angrily throws his friend out and climbs back into bed to get some much needed shut-eye. Edd, knowing Eddy is a lost cause, walks around the cul-de-sac and trips over a sign pointing to "Le Jimmy's Bee-Yooty Salon." Quickly, he enters and asks for a shower. Unfortunately, the only appointment Sarah will give him is in three weeks. Edd quickly rushes over to Jimmy and begs for an appointment, but Jimmy brushes him off. Edd then apologizes for acting out of character and tries to get to the bathroom, but a series of unfortunate circumstances causes Jimmy's shampoo rack to fall on both him and the current customer, Jonny. When they emerge from the mess, Edd asks Jonny for use of his shower, but Jonny refuses him as well. That is when Sarah gets ahold of him, and she proceeds to roughly toss our poor, sock-clad hero into a dumpster.
Distraught, Edd wanders until he comes across Rolf's house. There, Rolf is working in his garden. Edd tries to get Rolf's attention, but is unable to, as Rolf has put potatoes in his ears as ear protection. The best Edd can do is land in a pile of manure. At this point, he begins to go a little bit kooky. He wanders around the Lane uttering the words "Shower, shower, shower..." over and over and writing it on the walls with his filth-covered hands. When he finds a can of garbage, instead of shying away he simply dumps it on himself and wallows in the filth. When a ghost of his consciousness appears, telling him to shun the filth, Edd breathes on it, and the stench chases it away.
Nazz then appears, taking out her garbage. The filthy Eddward gleefully runs up to her, grabs the bag, and spills it all over himself. Nazz, shocked, tells Edd that he needs a shower and leads him into her house. At this, Edd starts to regain his sanity, glad at finally being able to get a shower. When he enters the bathroom, all is great, as the bathroom is clean and polished. Nazz leaves him alone, and Edd goes to look at the shower and get it ready. When he does, he's met with a surprise: in the shower hang several pairs of ladies' underwear. There is no chance Edd can shower here.
We then see that Eddy has gotten up again and taken a shower. This time, he's well-rested and happy. When he looks out the window, he spots Ed, about to bathe a filthy Edd in a washtub. Eddy and Ed laugh at Edd's predicament; fully sane, Edd will get a bath, but it's guaranteed to be completely unenjoyable.
Eddy: "Hey, Rip Van Winkle! Get cracking will you? We're late for school!" Ed: "The early bird catches the peanut, Double D!" Edd: "School? I hate to be the bearer of bad news, gentlemen" [pulls out a calendar] "but today is Saturday." Eddy: "Saturday?! Ed, you dolt!" [Eddy jumps off of Edd's window, angry at Ed] "You woke me up for school on a Saturday?!" Ed: [in flimsy defense of why he woke Eddy early on a Saturday] "It wasn't my fault, Eddy! My belly told me it was Bottomless Gravy Day at the cafeteria!" [grabs a swatter out and starts smacking his stomach] "Bad belly! Baaaaad!" [Eddy grabs Ed's spatula and hits Ed repeatedly on his head, pounding him into the ground.] Eddy: "Your HEAD's bottomless!"
Edd: [in horror after seeing what's left of his bathroom] "My bathroom! Demolished! Dismantled! Disintegrated!" [seeing a sticky note on the bathroom's support beam] "A sticky note." [reading the sticky note] "Dear Eddward, the shower is out of order due to renovations. Have a nice day. Love, Mother and Father. Oh dear…"
[Rolf takes two potatoes out from his ears, bites them, and sniffs them to be certain.] Rolf: "Ah. Too early, yes? The fermenting has yet to begin." [puts back the potatoes in his ears and continues to drill into his own backyard; Edd gets out of the cow manure and onto the lane]
Edd: "THE MILK OF HUMAN KINDNESS HAS ABANDONED ME!!!" [Edd sobs as he wanders helplessly into the lane, losing his sanity. He then writes "Shower" on the fences over and over using the dirt and grime on his hands.] Edd: "Shower, shower, shower... Shower, shower, shower... Shower, shower, shower! SHOWER, SHOWER, SHOWER!! SHOWER, SHOWER, SHOWER!!!" [Edd's left eye twitches as he finally goes insane and starts dirtying himself.] Edd: "Greetings microorganisms! Hop aboard! Welcome, bacteria!" [putting a dirty fish head on top of his head] "Oh, happy day!" Edd's Clean Hallucination: "EDDWARD! What are you doing?" Edd: "Dive in ol' vision of my former self! There's enough filth to go around!"
Ed: "Look what I found on Nazz's lawn, it looks a lot like Double D." Eddy: [sniffing Edd and recoiling from the horrible stench] "P.U.! You reek, Sockhead!" Ed: [looking at Edd] "He smells worser than the sandwich under my bed, Eddy!" Eddy: "You got that right, lumpy! More like your three month old gym socks!" Ed: [happily] "Oh! Oh! Like my head on a rainy day, huh, Eddy?" Edd: [sarcastically] "Ha ha ha! Can we get on with this, please?" [Ed puts dirty Edd into the tub of water. It instantly turns black and foul.] Ed: [walking toward the cowering Edd while holding a cheese grater] "Let's get that custard out of your bellybutton, mister!" Eddy: [offscreen in the background] "Wait, Ed! Let me go get a camera!"
Goof: Edd's upper window was opened up by Ed's shoe flying inward. But when Edd heads over to the window and sees Ed and Eddy outside, the upper window is closed.
Due to a mistake by Cartoon Network, this episode aired on October 1, 2005, a month before Season 5 was supposed to start.
Jimmy had his third scam in this episode (the first two appeared in "Ed in a Halfshell" and "Stuck in Ed"). This one, however, appears to be his least successful scam, as he runs into his shampoo rack and ruins his own salon.
It is revealed that Edd has a hat for every day of the week, as labeled on his rotating hat display.
This was the first episode to be co-written by the show's new head writer, Rachel Connor.
This is the second time Nazz's bathroom is seen. The first time was in the previous episode, but only part of her bathroom was seen then.
When Edd read the note, if you look closely the note says "love Mom and Dad," but he said "Mother and Father," which is what the sticky notes usually say. This is the first time the note says "Mom and Dad" instead of "Mother and Father."
In the scene where Ed prepares to clean Edd, the background music is similar to the music played in the scene selection menus on the Ed, Edd n Eddy DVDs.
Rolf usually has one cow and one pig, but in this episode it is shown Rolf owns two cows and pigs.
Apparently, Edd's skin gets irritated when he uses polyester towels.
It is revealed that this episode takes place in October (as shown on Edd's calendar).
Edd usually sleeps with his sock-like trademark ski cap, but at the beginning of this episode, he slept with a different hat on.
The music played in Jimmy's beauty salon was from "An Ed is Born."
