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. 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.

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?
Buzz's severed arm: 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 innocently shrugs and throws both his hands up...exposing the severed arm.)

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.
