Having a bad day?

Sing this. Out loud, or else it won't work. The more people who hear you, and the more inappropriate it is, the better you'll feel.

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 boy!

Feel free to change the gender nouns if you're more comfortable that way. But you'll probably have a hard time rhyming the last stanza if you do.
