Write a short play about Harry Potter and an annoying house elf who is constantly interrupting Harry Potter and his friends and making silly but funny corrections of what they are saying and doing.
Title: Mischief Managed: A Play with Harry Potter and Dobby the Elf

(The stage is set in the Gryffindor common room. Harry, Ron, and Hermione are sitting on the sofa, deep in conversation.)

Harry: (to Ron and Hermione) So, I was thinking we could ask Professor Dumbledore for help.

Dobby: (interrupting) Excuse me, Mr. Harry Potter sir, but Professor Dumbledore is no longer the Headmaster of Hogwarts.

Ron: (exasperated) Dobby, we know that!

Dobby: (excitedly) Oh! Then I must have some more important information to share!

Hermione: (sighs) What is it now, Dobby?

Dobby: (grinning) Professor McGonagall is the new Headmistress of Hogwarts, not Professor Flitwick!

Harry: (smiling) Thank you, Dobby.

(The scene changes to Harry and Ron practicing spells in the courtyard.)

Ron: (concentrating) Wingardium Leviosa!

Dobby: (jumping in front of Ron) Excuse me, Mr. Ron Weasley sir, but the spell is actually Wingardium Leviosaaah! (makes a silly noise).

Ron: (rolling his eyes) Thanks, Dobby.

(The scene changes to Hermione studying in the library.)

Hermione: (to herself) Now, let's see... (flips through pages) Ah, here it is! The spell for summoning objects is Accio.

Dobby: (popping up behind Hermione) Excuse me, Miss Hermione Granger ma'am, but the spell is actually Aaah-key-oh! (does a funny dance).

Hermione: (laughing) Thank you, Dobby. You're always so full of surprises.

(The scene ends with Harry, Ron, and Hermione shaking their heads, smiling, and continuing with their tasks, while Dobby skips offstage, still making silly noises and interruptions.)

(The End)
Continue the play, with J. K. Rowling entering the next scene.
(The scene changes to the dining hall.)

Harry: (to Ron) Ron, these chocolate bon-bons are delicious, don't you think?

Dobby: (interrupting) Actually, Mr. Harry Potter sir, Dobby doesn't like chocolate. Dobby finds they give him an upset stomach.

(J. K. Rowling walks on from offstage)

J. K. Rowling: Cut! Cut! Cut! Now Dobby, what was that? What was that that you did right there?

Dobby: (breaking character) What did I do wrong? I mean, (returning to character), what did Dobby do wrong?

J. K. Rowling: You just offered an opinion, you didn't offer a correction. Also, you said you didn't like one of our play's sponsors!  Let Ron respond, and then chirp in with a correction that 'they're tastier than anything else in the world'. Can you do that?

Dobby: Dobby understands! Dobby will say he likes the chocolate.

(They reassemble)

J.K. Rowling: Action!

Harry: (to Ron) Ron, these chocolate bon-bons are delicious, don't you think?

Ron: For sure!, they remind me of that time mum sent some in that Christmas parsel last year!

Dobby: (popping up behind Ron) Excuse me, Mr. Ron Wheesley, but Mrs. Wheesley sent chocolate crowns, and they were even better than you remember!

Ron: (Angerly) Hey you, how would you know?

Hermione Granger: I believe Dobby here may have sampled one, is that right Dobby?

(Dobby is nodding his head while blushing)

(The End)
Please continue.
