2DTV subverted this gag twice with footballer Roy Keane. Gis shoulder devil egs him on to kick Micheal Owen in the groin.

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.

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.)

Avatar: The Last Airbender : In "The Earth King", Zuko has a fevered dream of red and blue dragons representing his uncle and sister, 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 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!

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.

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.

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 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".

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.
In Slacker Cats Eddie uses his hands to pretend to have the angel and devil when deciding on things. The "angel" points out that he's simply there for show and nobody listens to him anyway. At one point Eddie decides on something rather horrible and both the angel and devil are disgusted.
