"Flea-Bitten Ed" is the 20th episode of Season 1 and the 20th episode of Ed, Edd n Eddy. In this episode, the Eds start up a pet boutique scam at Eddy's garage. They ask Rolf if they can clean up his animals for cash and he complies. While the Eds are cleaning the animals, Ed's allergy to rabbits wreak havoc on the scam, so Edd and Eddy try to find a way to make their friend feel better.
Ed is nailing a sign to the garage while Eddy lazes around. When Eddy looks up to inspect Ed's handiwork, he registers a complaint: the sign is upside down, and Ed needs to flip it. Hearing this, Ed flips "it", but takes "it" to mean the garage. The garage is upside down, but the sign is legible, and Eddy declares that Ed's Pet Boutique is open for business.
The Eds then head out to Rolf's place, reasoning that Rolf will have plenty of dirty animals for them to clean. When they get there, they find that this is indeed true, and after a short spiel from Eddy, Rolf agrees to let the Eds clean his animals. The Eds take the animals back to the garage and start to clean them. To help, Edd rigs up a chicken shower for the chickens, Eddy polishes Wilfred's behind, and Ed works on cleaning the cow. Once Wilfred is done, Edd suggests that Eddy get to work on the goat, and Eddy bathes Victor in the laziest manner possible. Edd then hears Ed ask for eyeliner; when he looks over, he realizes that Ed has put lipstick on Rolf's cow. Worried, Edd shuffles Ed off to take care of the rabbits.
According to Ed, these aren't rabbits, but rather bunnies. He rubs the two on his face and then starts to sneeze. In the ruckus, the bunnies escape into his shirt and run around his body. Ed laughs, and the bunnies end up on his head. Strangely, though, there are now four. Confused, Ed asks how many he was supposed to wash, hears the answer of two from Edd, and is stumped by the sudden appearance of extra rabbits. Ed writes this off as just weirdness and laughs happily. Suddenly, though, he sneezes. This is followed by another sneeze, which he stifles, and then purple blotches popping out all over his body followed by his body expanding ridiculously.
Edd draws Eddy's attention to this, and Eddy calls on Ed to get down, as Ed has begun floating. Ed is unable to control himself, though, so the Eddy gets on Edd's shoulders and grabs at Ed. He grabs onto Ed's shoelaces, but Ed starts floating out of the garage, taking Eddy with him. Eventually, Edd is able to catch his friends, and Edd and Eddy drag Ed back to the house for testing.
Edd performs a series of tests on Ed, helped by "Nurse Eddy". After an examination of Ed's skeleton and looking at Ed's body, Edd holds up a bunny as the final test. Ed is initially excited, but he soon begins to tear up, and the doctor and nurse dive behind the couch to avoid his sneeze. Seeing this, Edd concludes that Ed is allergic to rabbits. Not only that, but Ed has begun itching. To relieve this, Edd suggests cold cream, and they start to apply it, but Ed is still itchy. Ed then mentions that his mother uses talcum powder for itching. Out of options, the other two put talcum powder on Ed, and it relieves his itching; however, his swelling is still there. Edd's suggestion is ice, and the liberal application of a giant ice pack soon has Ed back to his regular size.
After placing Ed in an allergenic containment unit, the Eds head back to finish the job. When they open the garage door, however, they find that (in Edd's words) the bunnies have been practicing their multiplication tables. The rabbits then proceed to pour out of the garage in a tidal wave and consume the cul-de-sac, overwhelming Jimmy, Jonny, Plank, and Kevin in short order. Seeing that bunnies have taken over, the Eds go to watch TV; due to the rabbity overrun of the cul-de-sac, however, they have to move to Edd's roof in order to watch, which means that they'll have to deal with a few cries for help from the other citizens.
Eddy: "Rolf's got tons of stinky animals." Edd: "They're absolutely filthy!" [Ed pops up.] "Ow!" Ed: "Yes I am!" Rolf: "Goodbye!" [Rolf dips the hot iron chicken shoe into some water to cool it.] "Look here!" [sees the Eds] "Ho-ho! Hello, sneaky Ed boys! I am much too busy making shoes for my chickens, so no time for Rolf to talk. Work is good." [The chicken flaps its wings, but it stays put because of the shoes' weight.] "And good is a stomach full of Mama's cooked food. But you would not know this. Goodbye." Edd: "We're here to assist you, Rolf, and…" Eddy: [cutting Edd off] "You've got a lot of dirty animals there, Rolf. And we have the only pet-cleaning service in the neighborhood." Ed: "I put up the sign." Eddy: "So for a little green, we'll make your dirt-stained, flea-infested animals clean!" Edd: [alarmed] "Flea-infested?" Rolf: "You must be poking my eggplants! That would give me more time to watch the curd rise from the cheese of my grandfather's vats! Okay, Ed boys!"
Edd: [noticing Ed's allergies] "Eddy, Ed is showing strange symptoms. I'm concerned." Eddy: "I've been concerned about Ed from the first day I met him."
Ed: "AH-CHOO! I sneezed." [Ed begins to grow purple hives all over his body. He gasps.] "I'm mutating!"
Eddy: "Anything good on, Double D?" Edd: [scouring TV listings on a TV guide] "Ooh. There's a documentary on mollusks." Ed: "Boring! How about 'Barf: Defender of the Bunion People'?" [The Eds hear the kids yelling and screaming for help in the sea of bunnies.] Eddy: [yelling at the kids] "Hey! Shut your yaps! We're trying to watch TV here!" Sarah: [offscreen in the sea of bunnies] "Mommy!" Kevin: [offscreen in the sea of bunnies] "Hey, dork!" Eddy: "Some people are so inconsiderate." Jonny: [offscreen in the sea of bunnies] "Whoa!" Sarah: [offscreen in the sea of bunnies] "Ed!"
Edd: "We need to protect you from those allergies, Ed." Ed: "Jimmy cracked corn and I don't care."
Ed: "Hammer a nail, hammer a nail, hammer a nail, hammer a nail, hammer a nail, hammer a nail, hammer a nail. How's it look, Eddy?" [The nails Ed had in his mouth fall while he's upside-down.] Eddy: "Ed, you put the sign on upside-down!" Ed: "No, I put the sign on the garage." Eddy: "Just flip it over, Ed." Ed: "Flip it? Got it!" Edd: "I think I'm ready to tackle anything with my fine assortment of short and long, hard and soft hair brushes." [Edd and Eddy hear rumbling and see that Ed has flipped the garage over.] Ed: "I flipped it, Eddy!" Edd: "Well, I can read it." Eddy: "Ed's Pet Boutique is open for business!"
Eddy: "We've wasted too much time! Let's get these animals back to Rolf so we can collect our loot!" [He opens the garage door to find that the garage is now literally filled to the brim with rabbits.] Ed: "I'll take the one on the left." Edd: "Seems like Mr. and Mrs. Bunny have been practicing their multiplication table." [The garage explodes as the Eds are buried under thousands of rabbits.] Ed: "OH NO!" Eddy: "AVALANCHE!"
Jonny: "Got any fours, Plank? Go fish? Are you holding out, Plank?" [The wave of bunnies topples the fence.] "Plank!" [running from the tidal wave of bunnies] "I told you bunnies would take over the world! And they have!" [riding the wave over a fence] "Lucky we prepared for this day, huh, Plank?"
On the table showing the brushes, one of the brushes is labeled 00.5, when it should be 0.05. Also, the decimal is missing in the 2.0 label.
When Edd was cutting the chicken's toenails, the toenails didn't seem to get any shorter.
When Edd is saying "One, two, rest!" over and over at the chicken wash station, his mouth does not move.
When Edd is washing the chickens on the conveyor belt, the belt is moving in a stop and go pattern with manual power, but in the next scene, it is going in a nonstop pattern. In addition to that, when the conveyor belt is moving in the non stop pattern, Edd is nowhere near the controls in that situation. It is possible that Edd was only using manual power in order to later set the controls in an automatic position.
Before Eddy kicked the sprinkler underneath Victor, he was seen wearing white socks. In the next shot of his right foot kicking the sprinkler, the sock is the same color as his skin.
When Eddy was talking to Edd, his sunglasses disappeared, but when Edd boosts up Eddy, his sunglasses reappeared.
Edd's mouth didn't move when he said "Ow!" when Ed came right under Eddy and smacked his chin.
When in Eddy's living room, Ed is tethered down by all four of his limbs. However, he somehow manages to remove the flashlight from his mouth using his right hand, even though it reappears as tied down when the camera shifts.
When Eddy said "So now what, Doctor Double Meat Patty?" the red and white stripes on Ed's shirt are the same color as his skin.
When Kevin sees the riot of rabbits and says "What the–," the words don't match the flow of his mouth.
When Eddy yells out "HEY! Shut your yaps! We're trying to watch TV here!," the boutique sign is hung above the garage and the garage is open, but in the very next shot (when the bunnies have flooded the Cul-de-sac), the sign is missing and the garage is closed.
While Eddy is yelling for Edd to stop blowing ice, although Ed is still big, his purple hives have disappeared. However, this may have been because the cold cream had taken effect.
On the wall of Eddy's garage are labels that say "666-FIL" and "Texas."
When Ed falls down because of the rabbits playing with him, if one listen closely, you can hear a "Whoa!" in the background that sounds a lot like Eddy.
If you look closely when they show Ed's bloated skeleton to find out what's causing those symptoms, Ed's eyebrow has a bone and his skull is regularly shaped. However, in "Boom Boom Out Goes the Ed," his skull is shaped as buttered toast instead of a regular-shaped skull.
