"Is There an Ed in the House?" is the 3rd episode ofSeason 4 and the 80th episode of Ed, Edd n Eddy. In this episode, Sarah is sick and Ed and Jimmy both compete against each other over who's a better caretaker.
Eddy's latest scheme, Ed's Photography Studio, has attracted the attention of Rolf, who wishes to get his portrait taken and send the results to his family back home in The Old Country. Of course, Eddy likes to do things cheap, so instead of using an actual camera, he's having Ed draw up the pictures. Unfortunately, Ed has a wild imagination, and in his initial draft he puts a "four-legged mutant bus driver" behind Rolf. At Eddy's instruction, he erases it, but is soon interrupted by Jimmy, who wants to know where Ed's family keeps various items. Eventually, a fed-up Eddy tells him to go bug Sarah, and Jimmy reveals that Sarah is sick. Both Ed and Edd leap into action upon hearing this, ready to help Sarah in any way possible.
Soon, Eddy is watching impatiently as Ed and Jimmy try to comfort Sarah, only becoming more irked when Doctor Double D gets on the job and diagnoses Sarah as having a cold. His advice is that they vacate, as colds are quite contagious, and Ed moves to have his friends removed from the premises. When yet another "emergency" calls Ed back to his little sister's side, though, Eddy complains that they'll never get any work done, prompting Edd to contemplate setting up a paging system.
Naturally, Eddy loves the idea of not having to be stuck around Sarah all day, and soon Edd is at work creating the system. Sarah is tough to satisfy, though, and after some troubles with rigging it up for her maximum convenience, Edd gets fed up and calls her out on her selfishness. Sarah's response is to blow him a raspberry, which makes a germophobic Edd want to kill her. As a caring big brother, Ed can't let this happen, and he takes his friends out of the house. Eddy doesn't mind, though, as at least now he'll be able to set up his new scam: The Triple E Free Driving School.
Of course, this school won't be free, but it will (supposedly) teach the kids how to drive in a makeshift vehicle Eddy has rigged up. Edd is going to be the driving instructor, and Ed will naturally be the motor. Soon, though, Sarah pages for help, and Ed runs off. He returns shortly, and by this time, Jonny and Nazz are ready to go.
All is good, especially when Jonny mentions that Plank wants an obstacle course, which gives Eddy just the excuse he needs to tie up Jimmy and leave him on the pavement. The first customer in is Nazz, who is directed by a nervous Edd as Ed pushes the car. All seems to be going well until Edd's paging system interrupts again and Jimmy somehow manages to break free of his bonds. Needless to say, Ed has to help his little sister, and the motor runs off, leaving Edd and Nazz behind in an uncontrolled car. To make things worse, there is no brake.
This time, Sarah is demanding sustenance. Jimmy starts to feed her a grilled-cheese sandwich, but Ed bursts in and stuffs fruits and vegetables into Sarah's mouth. This starts a competition where they help her chew. Soon, though, Sarah needs something else: in this case, a story. Jimmy goes off to get the storybook, but Ed already has a story planned, in this case the tale of Zorba. Soon they start fighting over their stories.
Good and fed up, Sarah shows them a ball, throws it out the window, and tells them to go get it. Both chase after the ball, along the way passing the wreck of the car. By now, Eddy is fed up with this charade, and he demands Ed tell him what's going on. In response to Ed's blabbering about Sarah, balls, siblings and having to do what Sarah says, Eddy tells him that as since Ed's the big brother, he is the boss. This inspires the fighting spirit in Ed, and he pulls his pants up and prepares to enter Sarah's room.
When he enters Sarah's room, he sees Sarah and Jimmy playing. At first, Sarah makes fun of him, but soon Ed grabs the ball and tosses it out the window, yelling at her to rest. Jimmy offers to help, and Ed agrees by tossing Jimmy out the window. This makes Sarah sad, though, and if there's one thing big brothers can't stand, it's to see their little sisters in pain. The reverse doesn't work, though, and soon Sarah is laying a beatdown on Ed while outside, Edd is coming down with Sarah's cold. Jimmy comes over to help Edd, and Eddy looks around and decides to just go watch TV.
Edd: [setting up Rolf's photo] "Lets pick a theme, shall we? Would you like to pose with this beach ball or this sumptuous lollipop?" Rolf: "No sump! As Rolf prefers to turn his churn of soft spreads." Eddy: "There, he picked! Now get out of the way so I can take the picture!" Edd: "Okay Rolf, now look at me and smile for the tawdry sockpuppet."
Edd: [looking at the picture Ed has drawn] "Uh Ed? What is that behind Rolf?" Ed: "Rolf's head is about to be crunched by a 4-legged mutant bus driver!"
Jimmy: [plumping Sarah's pillow] "Am I a good fluffer, Sarah?"
Jimmy: [to Edd] "Sarah's got a fever Mr. Smartypants." Ed: "Yeah, Mr. 'I wish I was a smartpants'."
Eddy: "Ed! How can you be so stupid?" Ed: "I watch cartoons, Eddy."
Eddy: "The Triple E free driving school! Only it's not free, we'll charge 'em. Double D, you're the instructor." Edd: "Me? But I–" Eddy: "Ed, you're the motor." Ed: [ecstatic] "I have achieved greatness!"
Jonny: "Where's the obstacle course Eddy? Plank really wants to tear up the pavement!" Eddy: "Coming right up, Jonny boy!"
Ed: "Uh, pain and hurt! Have mercy, depraved sibling!"
Edd: "Curse you, cold microorganisms! Oh, it's all part of the big plan, don't you see? They wait and strike when you're most vulnerable–" [He sneezes again.] Jimmy: "Jeepers! You sound sick, Double D! You shouldn't be outside; you need some TLC, mister!"
When Edd introduces himself as "Eddward" to Nazz during the driving school scam, he has a name tag on. In the next shots, his name tag is gone.
Right before Sarah rings the bell during the driving school scam, Ed has only one stripe on the sleeve of his jacket. After Sarah rang the bell, it was back to normal.
Ed pulled his pants up when he went to Sarah's bedroom, but when he got there, his pants are at their normal level.
When Edd sneezes on Eddy at the end of the show, he develops a bloodshot eye. When Jimmy takes him away, however, his eye is normally colored.
