This part is sung by Annie:

I feel petty, oh so petty,
I feel petty and scheming and fey,
And I pity anyone who dares to get in my way.
I feel alarming, oh so alarming,
It's charming how alarming I feel,
And so nasty I can hardly believe I'm out of jail.
See that vicious face in the mirror there,
Who can that spiteful girl be?
Such a cruel face, such a short dress,
Such a cruel smile, such a short fuse.
I feel stunning--also cunning--
I feel like gunning down Meg with great joy,
For I'm in love with the man that she chose.

This part is sung by Meg:

Have you met my arch-rival Annie,
The craziest girl on the beach?
You'll know her the second you see her--
She's the one who clings to Ben like a leech.
She thinks she's in love, she thinks she's a brain,
She isn't in love, she's merely insane!
It must be the heat, soap-opera disease,
Elaine's waffles to eat, or maybe rabies.
Stay away from her--that means you, Ben--this IS the woman in the window:
Vain and impure, rude and unrefined,
Ill-bred and immature, and out of her mind!
