Works best when you know there is no way in hell that the wearer of such a thing is a schoolgirl...

I think I'll let the immortal bluesman Sonny Boy Williamson speak for me on this one.

"Good morning little schoolgirl,
Can i go home with you?
Tell your mama and your daddy,
That i'm a little schoolboy too.

Baby i love you,
I just can't help help myself.

You're so good looking pretty babe,
I don't need nobody else.

Good morning little schoolgirl,
Can i go home with you?
Uh, uh, uh...

I'm gonna leave you baby,
About the break of day
On account of the way you treat me,
I've got to stay away.

A good morning little schoolgirl,
Can i go home with you?

Tell your mama and your daddy,
That i'm a little schoolboy too.

Come on pretty baby,
Oh you know i can't help myself.
Uh, uh, uh...

I'm gonna buy me an aeroplane,
To fly all over your town.
And tell everybody baby,
Lord knows you've been putting me down.

I can't stand it babe,
Just cannot help myself

Your're so young and pretty,
But you're lovin' somebody else

A good morning little schoolgirl,
Can i go home with you?
Uh, uh, uh...
Oh babe what you do to me,
I can't help myself."
