AN: SO it's a Sirius is insane song. I Feel Pretty from West Side Story
Disclaimer: I own nothing

Sirius
I feel pretty, Oh, so pretty,
I feel pretty and witty and bright!
And I pity Any girl who isn't me tonight.
I feel charming, Oh, so charming
It's alarming how charming I feel!
And so pretty That I hardly can believe I'm real.
See the pretty girl in that mirror there:
Who can that attractive girl be?
Such a pretty face, Such a pretty dress,
Such a pretty smile, Such a pretty me!
I feel stunning And entrancing,
Feel like running and dancing for joy,
For I'm loved By a pretty wonderful me!

Marauders
Have you met are good friend Sirius,
The craziest guy in school?
You'll know him the minute you see him,
He's the one who is in an advanced state of shock.
He thinks He's in love.
He's thinks He's in Spain.
He's isn't in love, He's merely insane.
It must be the heat Or some rare disease,
Or too much to eat Or maybe it's fleas.
Keep away from him, Send for the nurse!
This is not the Sirius we know!

Modest and pure, Polite and refined,
Well-bred and mature And out of her mind!

James (spoken) wait a minute wrong description

Sirius
I feel pretty, Oh, so pretty
That the city should give me its key.
A committee Should be organized to honor me.

Marauders
La la la la . . .

Sirius
I feel dizzy, I feel sunny,
I feel fizzy and funny and fine,
And so pretty, Miss America can just resign!

Marauders
La la la la . . .

Sirius
See the pretty girl in that mirror there:

Peter
What mirror where?

Sirius
Who can that attractive girl be?

Peter
Which? What? Where? Whom?

Sirius
Such a pretty face, Such a pretty dress,
Such a pretty smile, Such a pretty me!

Marauders
Such a pretty him!

ALL
I feel stunning And entrancing,
Feel like running and dancing for joy,
For I'm loved By a pretty wonderful me!
