A/N: These just got stuck in my head one day, and I finally decided to write them down. I have a bunch for each character, but I'll just stick with these few. I might post more later. Who knows?
Haiku

Draco Malfoy:

What are you, stupid?
Malfoys just don't DO haikus.
Get away from me.

Lucius Malfoy:

Did you hear my son?
Then why are you asking me?
Damn filthy mudblood.

Albus Dumbledore:

It is amusing
To see the Malfoys do what
They claim to not do.

Would you like a sweet?
Your face is quite comedic.
That's a lemon drop.

Harry Potter:

Wait, what' a 'haiku'?
Oh, yeah, thanks Hermione.
I think this is one.

Die, Voldemort, die.
You are a half-blood yourself.
Just do suicide.

Ron Weasley:

Wanna lose in chess?
As long as it's Wizard's Chess…
It's what makes me ME.

Sure I was jealous.
But I was totally wrong.
Won't happen again.

Hermione Granger:

The knowledge in books,
Ancient words and older tales,
I submerge myself.

Sirius Black:

Don't read the fifth book.
It won't happen until read.
Don't read the fifth book.

Millicent Bulstrode:

I swear I exist.
Hurt J. K. Rowling for me.
I want more damn lines.
