Buzz's severed arm: Hi ya, fellas. To infinity and beyond!
Let's say we have Bob, Carol, and Alice. This trope is for when Bob is pretending to have a conversation with Alice, even though Alice isn't actually there (or in certain cases may not even exist). The purpose of this is to convince Carol that Alice is actually there, to maintain some lie Bob is pulling. Bob may do this by holding a one-sided conversation with "Alice", or he may even attempt to imitate Alice's voice and hold both sides of the conversation. Depending on the situation, this may involve Bob actually partially/fully disguising himself as Alice to further the ploy.
May also involve that character changing clothes or seating positions to further the absurdity of the one-sided conversation.
Can involve a Paper-Thin Disguise, Of Corpse He's Alive, and Bad "Bad Acting". When done while on the phone, this is a Phoney Call. Can overlap with ...But He Sounds Handsome (where Bob is actually pretending to be Alice, and then talks about himself). Not related to Talking to Himself, surprisingly, which refers to Real Life voice actors playing multiple characters.
- Happy Heroes: In Season 3 episode 6, Little M. disguises himself as his own mother for a parent-student conference at school. He winds up having to make it look like both he and his mother are there at the same time, including making it look like the two are speaking to each other.

- Toy Story: Buzz Lightyear, who originally believed he was the real Buzz, has gone temporarily insane after having his worldview shattered when he found out he was just a toy. His (toy) arm gets broken off in attempt to fly; later, he throws the dismembered arm at Woody in anger. Woody has to convince the other toys (especially Mr. Potato Head, who's holding a string of Christmas lights that Woody intends to climb back to Andy's house and refuses to let the other toys handle it) that Buzz is okay. He hold's Buzz's arm out from behind a wall, as if Buzz was actually standing just behind the wall, and proceeds to (badly) mimic Buzz's voice while waving the arm around.
Slinky: Hey look! It's Buzz!
Woody: (Shaking the arm's hand) Yeah, hey Buzz. Let's show the guys our new secret best-friends hand shake. Gimme five, man! (Pantomines with arm)
Hamm: Something's screwy here.
Woody: So, you see? We're friends now, guys! Aren't we, Buzz? (as Buzz) You bet. Gimme a hug! (Woody makes the arm grab his neck and pull him forward in a hug) Ha, ha, oh, I love you, too.
Slinky: See? It is Buzz. Now give back the lights, Potato Head.
Mr. Potato Head: Wait just a minute. What are you trying to pull?!
Woody: Nothing! (innocently shrugs and throws both his hands up... exposing the severed arm.)
- Megamind: Megamind has a disguise hologram that makes him look like a normal human. At one point, though, he's in a situation where he has to pretend to be both simultaneously.

- The Pixar short Geri's Game: Geri plays both sides of a game of Chess, getting up and switching sides of the table to do so.

- In Mighty Like a Moose, Mr. and Mrs. Moose each get plastic surgery on the same day, without telling each other. After their procedures, they fail to recognize each other—and they make a date. After figuring out that his girl is actually his wife, Mr. Moose scares her to death by rapidly changing in and out of a robe and putting on/taking off his fake teeth, tricking her into thinking that both men are in the house. He then goes so far as to stage a fake fight, in a long comic sequence that has him tussling around a doorway. Amusingly, she gets bored with the fight, even before she reads a newspaper plastic surgery advertisement and finally figures out that her husband and her would-be lover are the same person.
- The Mysterious Lady: Boris the bad guy tells Tania that he just arrested Karl, the good guy. Tania shoots Boris dead, Boris collapsing into a chair.

- Done hilariously in The Big Bang Theory, when Leonard, as part of an angry rant to Sheldon about his relationship troubles with Penny, fakes a conversation, giving her a classic Dumb Blonde Alpha Bitch voice. This is the result:
Leonard: I mean, what's she expect me to say - sure, Penny, have as many weird ex-boyfriends stay around as you like!
Leonard (as Penny): Okay like, sure Leonard, because, like I'm Penny, and I'm doing you a favor just by being with you (*the "conversation" continues in this vein for a while*)

Afterward, he mentions he has a different perspective because of "something Jimmy said".
- Monty Python's Flying Circus: Mr Mental collects bird watchers' eggs, then he does a rather poor ventriloquism of a TV interviewer asking questions and answering them.
- Stirring Science Stories: Due to the early issues of these magazines not having a fanbase yet, Donald A Wollheim used a number of Pen Names for submissions, pretending that they were different from himself as editor.

- This was used by Professor Gurwara in Strong Female Protagonist as a means of getting Alison to debate with herself as to whether an action she had recently carried outnote was ultimately justifiable. She then tries this for herself.
Alison [coat off] You didn't care when... when they told you about their life. About their story. You dismissed it.
Alison [coat on]: You're right. I didn't have the wherewithal to care about them, at that moment. Feral's pain, her suffering, the suffering of countless others had just been dismissed right in front of me. When I was asked to show the same level of empathy I had just been denied, I didn't have it in me. I knew who I cared about in the moment, and I made the call.
Coat off: But you're honestly telling me there's no other call you could make? You couldn't have given them time to consider?
Coat on: Every second that Feral was on that table...
Off: I understand that, but why not at least try to convince them first?
On: I did!
Off: You gave them the moral argument, sure, but you could have tried to persuade them, manipulate them...
On: What's so noble about that!? Me tricking them is your moral alternative? Say what you want about a half nelson, at least it's fucking honest! Charisma and intelligence are instruments of force just like strength, you can charm and bamboozle people into doing what you want, that doesn't make it right either! If anything it just robs them of the dignity of being able to resent you for controlling them!
Off: You're being dishonest right now. You know there is a middle ground somewhere in between a sterile approach to heroism and Machiavellian mind-control.
On: Yeah? Well I... I'm not any good at them.
Off: AND WHY MIGHT THAT BE!?
On: ...Because I've never had to be.
Off: "You've got to be careful what you get good at," that's what you said. Well the ace up your sleeve is turning you into a monster, or maybe it already has. For god's sake, you could have offered them something they wanted.
On: ...What could I have offered them that they didn't already have?
Off: I dunno. Understanding? Compassion? Trust?
On: Even if I was enlightened enough to have felt those things in the moment, what if they didn't work? There's no evidence to suggest that any amount of talking would have got Feral off that table.
Off: Well, I guess we'll never know.
On: Yeah, I guess we won't.
Off: ...Look, maybe it's naive to assume that there will always be a way to do things cleanly. No one-punch victories, right? In a messy, complex world, maybe the ends do justify the means. But the threat of living that way is that you pretty quickly stop looking for better means. I can admit that I'm glad to live in the world where Feral is happy and saving people.
On: I can admit that until violence is off the table, I'll always be quick to use it.
- Played very much not for laughs with the alantutorial episode "how to make double barrel ww2 italian fighter plane origami paper art," which has the distressed and mentally-deficient Alan angrily knocking on his own door while he pleads for just a moment to finish his video.

Homer: Oh, yes, of course. She's, uh, behind that plant. Hello, Marge. [ducks behind plant] Hi, Homey. [as himself] Sign this, please. [as Marge] You're the boss. [as Lisa] Daddy, ask the man for some candy. [as himself] Now, now, no candy for you. [as Lisa] Well, at least get some candy for yourself. [walks back to the teller] Heh, heh, heh, kids.

Martha lies that Mariella is stuck and then Mrs Demson wants to get her out so she lies that she got unstuck. She then does this, hiding behind the door to do Mariella's voice.
Mrs Demson: "Is she OK?"
Martha: "Are you OK? (as Mariella) I'm fine. (as herself) Are you sure? (as Mariella) I'm sure. (as herself) Absolutely? (as Mariella) Absolutely."

Martha: "I think she's just lost the use of her legs."
