Wolf: Say goodnight, Raquelle!
Raquelle: Goodnight, Raquelle!
What's New Pussycat? - Romy Schneider plays a language instructor teaching English to a mixed nationality group. Her fiance (Peter O'Toole) storms into the classroom, and as the two have a heated shouting match, the class repeats all their lines in unison. O'Toole finally shouts "Aaagh, you bunch of PARROTS!" and storms out.
In the Discworld series, the Ankh-Morpork City Watch Oath takes the cake for this trope:
"I comma square bracket recruit's name square bracket comma do solemnly swear by square bracket recruit's deity of choice square bracket to uphold the Laws and Ordinances of the city of Ankh-Morpork comma serve the public trust comma and defend the subjects of His stroke Her bracket delete whichever is inappropriate bracket Majesty bracket name of reigning monarch bracket without fear comma favour comma or thought of personal safety semi-colon to pursue evildoers and protect the innocent comma laying down my life if necessary in the cause of said duty comma so help me bracket aforesaid deity bracket full stop Gods Save the King stroke Queen bracket delete whichever is inappropriate bracket full stop."
One Crowning Moment Of Awesome for Sam Vimes is when he, while stranded in his own past, recites the whole thing from memory. He also implies that it's meant to be recited this way. (partially because Ankh-Morpork has been monarchless for centuries)
If you have trouble reading it, it should be:
"I, [recruit's name], do solemnly swear by [recruit's deity of choice] to uphold the Laws and Ordinances of the city of Ankh-Morpork, serve the public trust, and defend the subjects of His/Her [delete whichever is inappropriate] Majesty [name of reigning monarch] without fear, favour, or thought of personal safety; to pursue evildoers and protect the innocent, laying down my life if necessary in the cause of said duty, so help me [aforesaid deity]. Gods Save the King/Queen [delete whichever is inappropriate]."
A rare non-comedic example crops up in The Lord of the Rings, of all places, when Pippin peers into the Palantír and winds up on a direct hotline to Sauron himself:
'It is not for you, Saruman!' he cried in a shrill and toneless voice, shrinking away from Gandalf. 'I will send for it at once. Do you understand? Say just that!'
Live Action TV
The Burns And Allen Show always ended with George Burns saying, "Say goodnight, Gracie." The popular myth is that Gracie Allen would respond, "Goodnight, Gracie", this is a Beam Me Up, Scotty! She actually simply responded, "Goodnight."
From a Stargate SG-1 episode in which Daniel was turned invisible and only his grandfather Nick could see him:

Ed Hocken: All right, Eddie, let's say you did go to the movies.
All: You did go to the movies.

All: You were nowhere near the Club Flamingo.
In a Monty Python's Flying Circus sketch, Biggles tries to dictate to his secretary a letter to King Haakon, and explains that he is not dictating when he takes his antlers off, doing just that as he says so. When she repeats "I am not dictating," he says "What?" and asks her to read what she has been typing, which is:
"Dear King Haakon, I am not dictating. What?"
The very first Saturday Night Live sketch features this, albeit a physical version. Buck Henry plays a language tutor teaching an immigrant (John Belushi) how to read. ("I would like to feed your fingertips to the wolverines.") In the middle of a sentence, Henry has a heart attack and drops dead. Belushi looks at his dead body and slumps over the same way.
Hilariously taken to extremes in the Night Court episode "Here's To You, Mrs. Robinson". Harry is trying to swear the pregnant Quon Le and other foreigners as U.S. citizens while Mac has appendicitis.
Harry: All right then, at this time, I'm going to ask everyone to raise you right hand and repeat after me...
Mac: (bawls in pain)
Crowd: (imitates Mac bawling in pain)
Harry: Mac, are you all right?
Crowd: Mac, are you all right?
Harry: (making "stop" motion) No, no!
Crowd: (imitating Harry) No, no!
Then they try it again, but this time, they repeat Quan Le going into labor.
Played with in "The Human Duplicators", when the hero says to his girlfriend, "Say something." Joel and the bots chime in with "Something". They're then surprised when the girlfriend also says, "Something."
At the end of "The Indestructible Man", Joel reads aloud an affidavit that he and the bots have agreed to sign, stating that they will never make any more cop/donut jokes. When Joel reads, "I, state your name—" the bots immediately respond with "I, state your name—", much to Joel's chagrin.
Beakman: Let's say this wall represents a magnified section of human skin. Rizzo and Josie: This wall represents a magnified section of human skin. Beakman: Hello.
After Hello Cheeky's local pianist, Denis King, is pelted with tomatoes:
Denis: Another television first...I shall now play "Fascinating Rhythm" with an eyeful of tomato. (playing and singing)Oh, fascinating rhythm with an eyeful of tomato...
A Horrible Histories segment on how Victorian schools were run (by the students repeating whatever their teacher said).
In the episode of Being Human where George teaches English as a Foreign Language and has Hollywood Tourette's, he recounts an incident where he said "Repeat after me" directly before an involuntary Cluster F-Bomb. The students all did.
Dinosaurs: The Chief Elder has, among other responsibilities, the duty to name babies. When Earl and Fran brought Baby to be named, the Chief Elder started feeling pain and moaned. As the scribe in charge of writing the names on a certificate wrote the moans, the Chief Elder explained he was dying. Until a new Chief Elder was elected so the Sinclairs could take Baby to be renamed, Baby Sinclair's official name was "Ouch Ouch I'm Dying You Idiot Sinclair".
Another victim of the trope was Fran's cousin "Atchoo".
And "*Burp* Excuse-Me Finkleman"
The IT Crowd: Roy and Moss are worried about what to say to Denholm's widow at his funeral, and Jen tells them, "Just say, 'I'm sorry for your loss,' then move on." Roy goes up and says, "I'm sorry for your loss. Move on."
"C'est Si Bon" begins with Freberg trying to instruct (in a bad French accent) his backup singers to sing "si bon, si bon, like zat." He then tells them to sing "si bon, si bon, forget the 'like zat,'" and "si bon, si bon, period," with no better results.
In "I've Got You Under My Skin," each line of lyrics is dictated by Freberg to the chorus. When he starts forgetting what the lyrics are, they dutifully sing lines like, "Oh, darn it, what are those words?"
In Fred Penner's album Collections, he asks the audience to repeat after him and then cannot get them to stop.
A staple of Les Luthiers' shows. For instance, in "Cartas de Color", when Oblongo is teaching his nephew the rain dance:
Oblongo: Repeat my words. Pupils: "My words", "my words"...
McDonald's once held a promotion where they gave out little vinyl records, and you could win a million dollars if the choir on the record was able to successfully finish the The McDonald's Menu Song. The choir slavishly repeats everything Ronald McDonald says:
Ronald McDonald: Repeat after me! Choir: Repeat after me! etc.
Steve Martin had a stand-up routine where he would make the audience repeat "The Non-Conformist's Oath."
Badger: Repeat after me. I, name of animal... Toad: I, name of animal...
Animaniacs: Woe betide anyone who asks the Warner siblings to "repeat after me". They'll repeat everything, including the words "repeat after me". Of course, being the Warners, they obviously just do it to mess with whoever asked.
Used in South Park, where a ghostly minion of Satan is manipulating the Republicans, whispering in the ear of George W. Bush during a press conference. It all goes fine until...
Kevin: It is God's will that he live! Bush: It is God's will that he live! Kevin: Haaghaghaghaghaghagha... Bush: Haaghaghaghaghaghagha... Kevin: No no, you don't say that part, Haaghaghaghaghaghagha. Bush: No no, you don't say that part, Haaghaghaghaghaghagha.
Patrick: He really needs to get to the Great Beyond. SpongeBob: Patrick, say that again. Patrick: That again. SpongeBob: No, the other thing. Patrick: No, the other thing.

Mr. Krabs does this to Spongebob and Patrick when scolding them for playing on fish hooks in ''Hooky":
Mr. Krabs: I need a sailor's promise! Repeat after me. Yo ho, yo ho! Near the hooks, I'll never go. Spongebob & Patrick: Yo ho, yo ho! Near the hooks, I'll never go. * A fish hook points right behind Mr. Krabs* Mr. Krabs: Ayeeee! Mother of Pearl! Fire on the poop deck! Spongebob & Patrick: Ayeeee! Mother of Pearl! Fire on the poop deck!
Buster: Say good night, Babs. Babs: Good night, Babs.
During one episode of The Grim Adventures of Billy & Mandy, all the boys join the "Secret Snake Club''' in order to get out of gym class, and have to respond to an oath... but when the senior members get into an argument, everyone else keeps repeating what they are saying.
When Pinky ran for President, Brain typed stuff for him to read from special glasses during a debate. Unfortunately, the "F" button got stuck, prompting Pinky to make the sound. One of his opponents repeated it. Also, the glasses got other signs which Pinky repeated and another adversary tried to emulate.
The trope was the ruin of another plan from another episode where Pinky gained notoriety.
Principal Wartz: "Repeat slowly after me." Harold: "Slowly after me." Principal Wartz: "No! Not yet. 'I will not enter the school grounds for the next three weeks.'"

Harold: "Harold."
In the late, lamented Adventurers Club, this was a routine occurrence in the "New Member Induction Ceremony" segment. For instance:
Character: Repeat after me: *clears throat* Audience: *clears throats* Character: No, not that! Audience: No, not that! Character: Not that either! Audience: Not that either! (Cycle would continue until either the character involved got fed up or another character prompted them to continue.)
