Impersonating McGonagall…

Sirius: Ladies and Gentlemen. We are gathered here to ask an age-old question: Who here does the best impression of Professor Minerva McGonagall?
Sirius: You will be judged on voice, body language and flair. Everyone will perform the same scenario: Professor McGonagall eating a marshmallow for the very first time. Ready, set, McGonaGO!
[Impersonating McGonagall]
James: What is this glutinous monstrosity before me?
********
Lily: The sugar in this is quite sweet.
********
Peter: *high pitched sounds of pure happiness and joy*
James: … that’s your impression?
Peter: I can hear her doing that.
********
Remus: Looks like a sticky pillow.

Sirius: I don’t care for it. Classical Music.
*McGonagall enters*
McGonagall: What are you all doing?
Sirius: Professor, nothing. Care for a marshmallow?
McGonagall, taking a marshmallow: *high pitched sounds of pure happiness and joy, laughing*
Peter: I KNEW IT!
