Good Girls歌词：
Do do do d-do do do do do do
She's a good girl
She's Daddy's favorite
He's saved for Harvard
He know she'll make it
She's good at school
She's never truant
She can speak French
(I think she's fluent)
'Cause every night she studies hard in her room
At least that's what her parents assume
But she sneaks out the window to meet with her boyfriend
Here's what she told me the time that I caught her
She said to me,
"Forget what you thought
'Cause good girls are bad girls that haven't been caught.
So just turn around and forget what you saw
'Cause good girls are bad girls that haven't been caught."
Whoa oh oh oh- oh whoa oh
Good girls are bad girls that haven't been caught
Whoa oh oh oh- oh whoa oh
Good girls are bad girls that haven't been caught
She's a good girl
A straight A student
She's really into
All that self-improvement
I swear she lives in that library
But if you ask her she'll say,
"That's where you'll find me!"
But if you look then you won't find her there
She may be clever but she just acts too square
'Cause in the back of the room where nobody looks
She'll be with her boyfriend
She's not reading books!
She said to me,
"Forget what you thought
'Cause good girls are bad girls that haven't been caught.
So just turn around and forget what you saw
'Cause good girls are bad girls that haven't been caught."
Do do do d-do do do do do do
Good girls are bad girls and good girls are bad girls
Do do do d-do do do do do do
Good girls are bad girls and good girls are bad girls
She's a good girl
(She's a good girl)
Hasn't been caught
(She's a good girl)
She's a good girl
(She's a good girl)
Hasn't been caught... caught... caught... caught... caught... caught... caught... caught...
She said to me,
"Forget what you thought
'Cause good girls are bad girls that haven't been caught.
So just turn around and forget what you saw
'Cause good girls are bad girls that haven't been caught."
She said to me,
(She said to me)
"Forget what you thought
'Cause good girls are bad girls that haven't been caught.
So just turn around
(Just turn around)
And forget what you saw
'Cause good girls are bad girls that haven't been caught."
Whoa oh oh oh-oh whoa oh
Good girls are bad girls that haven't been caught
Whoa oh oh oh-oh whoa oh
Good girls are bad girls that haven't been caught
Whoa oh oh oh- oh whoa oh
Whoa oh oh- oh oh whoa oh
Good girls are bad girls that haven't been caught
