2DTV subverted this gag twice with footballer Roy Keane. His shoulder devil eggs him on to kick Micheal Owen in the groin. Resisting the temptation, an even bigger devil shows up and eggs him on to do worse, which he then does. Owen's shoulder angel peacefully tells the battered footballer not to retaliate, with a larger angel suggesting they should buy Roy some flowers.
In "Daffy Duck Hunt", a dog considers whether to let Daffy out of a freezer or not. The shoulder angels are arguing until the good angel tells the bad one to "Aw, shaddup!" and jams his halo down on him.

Inverted in the Treehouse of Horror story, "Attack of the 50-Ft. Eyesores." Bart sits on the shoulder of a giant Devil (really a mascot come to life). In his right ear, Bart tells him to destroy the school. He then goes to the opposite ear and says a similar message in a different voice.
In another episode (season 4's "Whacking Day"), Homer tells Lisa that inside man is a struggle between good and evil that will never be resolved. Cut to an Imagine Spot of Good Homer's grave as Evil Homer (really Homer in a devil costume) doing the cha-cha on Good Homer's grave, chanting "I am Evil Ho-mer!"
In "I Love Lisa," Homer tells Lisa to ignore her conscience, whereupon Homer's good angel appears and tells him that's a terrible thing to say. Homer responds with a dismissive "Shut up!", to which the angel replies with a dejected "Yes, sir!" before vanishing.
Homer has "Strict Homer" (a murderous police officer with a laser gun), "Funny Homer" (a drunk, partying Homer in rainbow suspenders), and "Intellectual Homer" (Homer in a sweater vest and a mortarboard) within his head, as seen in the episode "We're On The Road to D'oh-Where." The last of the three has been murdered years ago.
In "The Frying Game," after killing an endangered caterpillar, Homer's bad angel kills his good angel, telling Homer that now "they are in this together." Then they high-five each other.

When Moe refurbishes his bar into a gay lounge, he at first thinks of telling his new patrons that he's straight. The first one to pop up is his shoulder devil (essentially Moe dressed in a tuxedo with devil props), who encourages him to hide behind his homosexual façade, but when he says they should wait for what Angel Moe has to say, the devil replies: "I'm Angel Moe". Then, the real Devil Moe (a bestial-looking, hulking red demon) pops up on his other shoulder and devours Angel Moe before letting out a guttural, evil laugh.
In yet another episode, Homer is portrayed with 400 devils on his shoulder.
In "A Test Before Trying", Bart has to pass a standardized test or the school will be shut down.

His bad angel - his mother in a devil costume - doesn't even bother arguing and pulls the alarm herself.
In a couple of episodes of Garfield and Friends, Garfield has an angel and a devil that fight over what courses of action he should take. His devil usually uses every method he can think of to send the angel as far away as he can; the angel, in return, often reenters the scene a while late through unusual means. (Example: the devil mails the angel to Mexico. The angel later walks back through the door carrying luggage and wearing both a sombrero and a serape.)
Slightly spoofed in Lilo & Stitch: The Series, where Stitch undergoes the "two devil" variation when he ponders whether or not to get rid of an experiment stealing Lilo's attention away from him.
Avatar: The Last Airbender: In "The Earth King", Zuko has a fevered dream of red and blue dragons representing his uncle as the Good and his sister as the Bad, a scene which turns literal in the season finale. Also note the foreshadowing: his "Evil" Ancestor, Fire Lord Sozin, owned a Blue (or, blue-ish, at the very least) dragon, while his "Good" Ancestor, Avatar Roku owned a Red Dragon. Said ancestors were best friends, until the evil one left the good one to die under tons of volcanic soot.
In "The Donut of Shame", this trope is spoofed with an angel donut and a devil donut appearing on Patrick's shoulders.
The trope is parodied again in "Sportz?", where Squidward finds SpongeBob and Patrick playing with sports equipment incorrectly and is asked by them to teach them how to play sports properly. Squidward is advised by his angel to teach them how to play sports properly so they can't get hurt, while his devil sadistically gloats that Squidward has the opportunity to get back at the times SpongeBob and Patrick annoyed him by tricking them into getting hurt. Angel Squidward is forced to side with Devil Squidward after he gets hit by a tennis ball.
The short-lived show God, the Devil and Bob had a variation on this, where Bob was constantly visited by...well, guess, with the devil trying to prove that there was no good in humanity by focusing on Bob, a crude, loud-mouthed imbecile.
In the Daria episode "Lucky Strike" (where the teachers finally go on strike), Daria gets one of these moments after Ms. Li tries to get her to take the place of a substitute that her mother got fired when she discovered that he was flirting with Tiffany.
Devil Daria: Not so fast. You'll get out of gym class. Angel Daria: You? A scab? Devil Daria: Oh, great. Touched by an angel. Angel Daria: You'd be betraying your teachers. Devil Daria: Hey, yeah! You'd be betraying your teachers! Angel Daria: You'd just be falling into the same trap that managements always use to keep wages low and workers weak. Devil Daria: Oh, go dance on the head of a pin. You could make Quinn's life really miserable. Angel Daria: Huh. That's a good point. Devil Daria: Hey, you hungry? Angel Daria: Yeah, we can pick this up later. (the "devil" and the "angel" disappear)
In Father of the Pride, Larry (a lion), starving because of his diet, starts contemplating eating his best friend's girlfriend (a gopher). His Devil is a lion, but his Angel is a gopher, and thus barely gets to say anything before the devil eats her.
In some old Disney shorts with Pluto, Pluto has an angel and a devil, who were both dogs like himself; angel dog wore a halo and devil dog wore horns and a red cape. Devil dog usually encourages him to do things like disobey Mickey and chase cats.
A House of Mouse short features Pluto's angel and devil. Later, after Mickey punishes Pluto for making a mess (when it was actually three kittens who made the mess), Pluto's angel and devil start giving Mickey suggestions. And they don't just look like Pluto's; the Devil even mentions the kittens, which Mickey does not, at this point, know about.
They also appeared in another short that for some reason wasn't even aired with that show at all! In this short, Pluto's conscience persuades him into thinking that Minnie Mouse is out to get him after Mickey left him at her house while he was on vacation. Said conscience later makes him have nightmares about Minnie burying him alive, and even drags him to Hell!
Several Heathcliff and the Catillac Cats cartoons feature Heathcliff talking to his shoulder angels, in the end he usually ends up listening to his shoulder devil.
An episode has Nathan confronted by his Good Angel, Bad Angel-Murderface and Pickles respectively, at the dentist's office. Murderface claims that taking the knockout gas would leave you at the mercy of a molesting dentist, and therefore makes you gay. Pickles says it wouldn't matter, since you'd be out cold anyway.
Another episode had Pickles, now sober, locked in a room with a table full of booze while his bandmates are in danger. The good angel tells him he should go save his friends, the bad angel encourages him to start drinking. He does both.
In an episode of The Flintstones, Fred buys a sweepstakes ticket and shares it with Barney who is broke and unable to purchase one. Barney decides to guard the ticket.

A Spanish show called Lola and Virginia has used this with Lola, one of the main characters a couple of times. But they've done it a bit differently.
In one episode she asks a student from her friend's karate class to help get back a bracelet that another girl took from her. Lola's friend tells her that karate students don't go around beatin people up. Lola says that's not what she had in mind at all. She smiles innocently, but for a second she changes into a devil version of herself, with a black dress in place of her usual red one.
In another episode, Lola is in a contest to win a moped. A classmate is also trying to get it for his brother. Lola feels bad about beating the boy and imagines her devil self beating the boy to the top of a mountain using a helicopter, when he was climbing. Lola's devil self runs for the prize, but is held back by Lola's angel selfs, who restrains her by grabbing her tail. A moment later, when Lola helps the boy win and beat a girl who was cheating, her angel self and devil self actually high five each other.
A claymation short used after the first act of the episode "Totally Bogus Video" had Bogus being confronted by angel and devil versions of himself when he comes across a wrapped-up box of candy on the counter. The angel and devil then confront each other, which escalates into a Big Ball of Violence, giving Bogus a chance to help himself to the candy.
Another episode had Bogus chasing after an ant that had stolen his special piece of cake. When he finally catches up with the ant, he is both anguished and ashamed to discover that the ant had only stolen the cake because it was a baby ant's birthday. First, his bad side, who is depicted as a leather-clad Badass Biker, tells Bogus that they're just puny insignificant ants and that the cake is rightfully his for him to just take, before his good side, who is depicted as a Sesquipedalian Loquaciousness-spouting well-mannered philosopher, tells Bogus that if he just takes the cake back, he will regret it for the rest of his life. At the end of the discussion, Bogus ends up listening to his bad side and takes the cake from the ants anyway.
Spoofed in the episode "Ike's Wee-Wee", when both sides agree about Mr. Mackey drinking a beer.

Gives a little insight to how Weird Harold probably views his friends. (The Albert angel wins at the end of the episode by angrily grabbing the Rudy devil and hurling him into an arcade game screen.)

Spoofed in the Ed, Edd n Eddy episode "Brother, Can You Spare an Ed?" Ed is sent shopping by Sarah to buy some fudge at the candy store, but Eddy tries to convince Ed to buy jawbreakers for himself and his friends instead. Edd tries to convince Ed to do as his sister asked, and the argument is represented by a Shoulder Angel Edd and a Shoulder Devil Eddy trying to persuade Ed. However, different from a lot of the occurrences of this trope is the fact that the Shoulder angel/devil mirror all of Edd & Eddy's actions, right down to the two of them actually fighting.
Edd: Stand firm and deliver, Ed! Let integrity be your guide. Eddy: He's right, Ed. And "integrity" in Latin means "buying jawbreakers".
On the very first episode of Family Guy, Peter's shoulder devil appears - but the angel is missing, revealed in a cutaway to be caught in traffic.

At the end of the episode Rocko has caught a foul ball (which would have been ironically easier if he didn't move down) but a little kid asks for it. The devil tells Rocko to keep it while the angels says it is better to give then to receive and ensures Rocko gives by hitting him with a baseball bat.
