X-Men: The Last Stand2006

[The prison guard stumbles to Mystique, who was diguised as a president, in her cell.]

Mystique:
[as the President of the United States] Let me out of here! I demand that you release me! Do you know who I am? I'm the President of the United States.

Prison Truck Guard:
"Oh, Mr. President...." Shut up! [walks away. Mystique then shapeshifts as a little girl.]

Mystique:
[as a little girl; pretending to cry] Why are you doing this to me? Let me down. I'll be a good girl. Please let me go.

[The prison guard turns to Mystique.]

Mystique:
[as a little girl] Please.---

Prison Truck Guard:
[aims his pepper spray at her] Keep it up. I'll spray you in the face, b*tch.

[Mystique, still as a little girl, smiles.]

Mystique:
[as a little girl] When I get out of here, I'm gonna kill you myself.

Prison Truck Guard:
Yeah, right!

[The prison guard walks away as Mystique shifts back to her original form while smiling.]
