Note: this is to the tune of bare necessities

Hermione: (to herself in a potions class) Look for the perfect guy in life,

I'm sure his name is Harry,

but he don't see me staring in his eyes.

I mean I feel I love him so

But how do I just let him know

I need to be a great girl in his eyes

(Ron notices Hermione acting strange and starts whispering to Harry)

Ron: Just watch her eyes wander

Just watch her eyes roam

It just isn't like her I think she knows

Harry: The only thing she knows is we look gay in these black robes

She's no idea you're crazy for her, so stop acting so out of order

Hermione: A girl's necessities: to look pretty and smile sweetly

Shame my hairs a crazy freak of life
