"Fool on the Ed" is the 15th episode of Season 1 and the 15th episode of Ed, Edd n Eddy. In this episode, Eddy decides to prank all the other kids after he easily pranks Ed and Edd, but he and his friends soon find out that the kids of the Cul-de-Sac are being terrorized and pranked by the infamous "Prank Master." The Eds soon become terrified that they may be the next victims on his list.
The episode starts with Eddy sliding into Ed's room, where his friend is making a model. When Ed asks for the glue, Eddy goes to get it, but notices a trap. Eddy manages to firstly dismantle the trap and prank Ed, and then rig Ed's trap so that Ed is pranked again. They then head off to Edd's house, where they find him tinkering with a chemistry set. When the phone rings, Eddy does as Edd requests and goes to answer it, but senses a trap when he reads three sticky notes on the phone inviting him to pick it up. Eddy smartly pretends to pick it up and pretends to talk into it. When he insinuates that the call is for Edd, Edd is surprised and accidentally causes a chemical explosion. This isn't all for Edd, though; Eddy comes in and tells him that there's a girl on the phone for him. Edd swiftly rushes out–straight into a trap Eddy has set.
After Eddy has pranked both his friends, he marches up to them, bragging about how he is the king of pranks. He then suggests that he'll be able to prank every single kid in the cul-de-sac before sunset. His friends come with him on the expedition. The first stop is Rolf, who is busy feeding the hogs. Strange goings-on are afoot, however, as when Rolf steps into his shed for a minute, he is swiftly tossed out in a butter churn barrel. When the Eds rush over to check it out, Ed finds a card atop the barrel. On the card are written the words "Prank Master".
Eddy tries to shrug it off and goes to find his next victim. While walking down the lane, however, they run into Jonny, who is diaper-clad and hanging from a tree. The Eds laugh at this sight until Plank falls from the tree, with a familiar card tacked to his face. Ed pulls it off, and the signature from before is shown. The Eds are all fearful, but Eddy tries to disguise his fear by pointing out anyone could prank Jonny. When he looks back at the tree, however, Jonny has disappeared.
Eddy tries to get his friends to relax, but is unsuccessful since he as well is scared. The fear becomes too much for him, and he takes off running, his friends in hot pursuit. As they run, they encounter several other victims of the Prank Master, including Jimmy, Sarah, and Kevin. Trying to find a place to hide, they dive into the sandbox, only for Prank Master cards to rain down on them. Edd, terrified, notes that they're next.
When the Eds are next seen, they're wearing makeshift helmets and carrying basic weapons. They're also in an outside-facing ring in order to make sure nothing and nobody can creep up on them. Soon enough, they find something suspicious: a stray jawbreaker. While Ed wants to simply eat it, Edd and Eddy demand testing. Eddy therefore nudges it twice with his hockey stick. The second nudge is harder than the first, and the sweet rolls down the sidewalk to the curb, straight into the path of Sarah and Jimmy. Jimmy picks it up, licks it, and begins to eat it. Seeing this, Eddy realizes that the jawbreaker wasn't a fake at all, and they've lost their chance at one of the sweets. When he tries to blame it on the other Eds, however, Ed points out that Eddy was the one who thought it was a trap. In response, Eddy tells them to look another way and ties Edd's hat to his underwear. In retaliation, Ed wedgies Eddy, and both Edd and Eddy join in by giving Ed a pants wedgie. The Eds are all cheered up by this bout of wedgies, but soon their attention is drawn to the laughter of another group. This group is the kids, who reveal that there never was a Prank Master and that they all faked being pranked. Eddy is sickened by this, and angrily declares that he'll get the kids back as they walk off, leaving the Eds alone.
Later that day, the kids are playing in the Cul-de-Sac. Eddy isn't preoccupied with this, however, as he and his friends have more sinister plans. They are building an El Mongo Stink Bomb from a recipe Eddy's older brother had given. Once the final ingredient is put in, they ready it for deployment. The bomb moves forward towards the exit of Eddy's garage. It seems as though things will go off without a hitch when the bomb catches on the garage door and becomes stuck. The Eds desperately try to move it out, but are unable to budge it. The bomb explodes while stuck, sending atrocious fumes across the cul-de-sac and perhaps through the whole of Peach Creek. The kids are hit horribly by the stench and rush to get inside. By far the worst hit are the Eds, however, who were right next to the bomb when it went off. Dazed by the stink, they stumble outside and collapse on Eddy's lawn, victims of their own prank.
Edd: [giggling] "M-m-me?" [dropping the test tubes and heading towards the phone] "H-h-how do I look, Eddy?" Eddy: "It's a phone call, Romeo." Edd: [stepping on the roller-skates in mid-speech] "Thank you, ED-D-D-Y!"
Eds: "The Prank Master?!" Edd: [recoiling from the handwritten Prank Master card in Ed's hand] "He's such a horrible printer!" Ed: "Here! You hold it, Double D." Edd: "I have no idea where it's been!"
Eddy: [gleefully watching the fumes percolate through the stink bomb] "My brother showed me how to make it, before he went away. Isn't it beautiful?" Edd: "The odor should be quite impressive." Eddy: [offscreen in the background] "Just one more ingredient."
Edd: [after the El Mongo Stink Bomb explosion] "I CAN'T BREATHE!!!!!"
Ed: [reveling in the smell of the erupted stink bomb] "Ah, something smells good." Edd: [holding his nose] "It is said that scent is a gateway to one's inner essence." Eddy: [brain scrambled by the stench] "Yes! I stink, therefore I am!"
Usually Rolf has only Victor under his ownership. But this episode shows that Rolf has three other goats under his ownership. The other three goats he had could have been borrowed, though, as this is the only episode in which he owns more than one goat.
When Sarah yells "Mommy!" and falls through the trap door, there is no Prank Master card to be seen. In every other scene where a kid is pranked, a Prank Master card is seen.
Nazz only makes a small cameo appearance in this episode; she is seen with the other kids laughing at the Eds for falling for their pranks, but she was never seen being pranked.
This is the first appearance of the El Mongo Stink Bomb and its only appearance in the television series. It also appears in the video game Ed, Edd n Eddy - The Mis-Edventures and the online game Cul-de-Sac Smash 2: Wheels of Fury. However, in the former game, it is a lot smaller—so small that Eddy can hold it up and throw it. In the latter game, the stink bomb is used as Eddy's special attack. The El Mongo Stink Bomb is also mentioned by Edd in the movie.
The shot where Edd and Eddy give Ed a wedgie is the design of the CD cover for Ed, Edd n Eddy - The Mis-Edventures.
This is the second time Edd screams "I CAN'T BREATHE!": the first time was in "The Ed-Touchables."
This is the second episode where Kevin never uses the word "dork" or anything with the word "dork" in it.
When the Eds were making the El Mongo Stink Bomb at Eddy's garage, there's a calendar on the wall similar to the ape calendar Eddy came across in the trash from "Quick Shot Ed." However the calendar seen in this episode was not in color.
If this episode is played with English subtitles on the Fools Par-Ed-ise DVD, the subtitles think Rolf's shouting at the end of the episode is him saying "Yes! We're done!"
