LYRICS
You can dress me up diamonds
You can dress me up in dirt
You can throw me like a line-man
I like it better when it hurts
Oh, I have waited here for you
I have waited
You make me wanna la la
in the kitchen on the floor
I'll be a french maid
When I meet you at the door
I'm like an alley cat
Drink the milk up, I want more
You make me wanna
You make me wanna scream
You can meet me on an aero-plane
Or in the back of the bus
You can throw me like a boomerang
I'll come back and beat you up
Oh, I have waited here for you
Dont, keep me waiting
You make me wanna la la
in the kitchen on the floor
I'll be a french maid
When I meet you at the door
I'm like an alley cat
Drink the milk up, I want more
You make me wanna
You make me wanna la la
in the kitchen on the floor
I'll be a french maid
When I meet you at the door
I'm like an alley cat
Drink the milk up, I want more
You make me wanna
You make me wanna scream
I feel safe with you
I can be myself tonight
It's alright, with you
Cuz you hold, my secrets tight
You do, You do
You make me wanna la la, la la la, la la, la la la la la la la la la
You make me wana la la, la la la la
You make me wanna la la
in the kitchen on the floor
I'll be a french maid
When I meet you at the door
I'm like an alley cat
Drink the milk up, I want more
You make me wanna
You make me wanna la la
in the kitchen on the floor
I'll be a french maid
When I meet you at the door
I'm like an alley cat
Drink the milk up, I want more
You make me wanna
You make me wanna scream
You make me wanna la la, la la la, la la, la la la la la la la la la
You make me wana la la, la la la la
You make me wanna la la, la la la, la la, la la la la la la la la la
You make me wana la la, la la la la
You make me wanna la la, la la la, la la, la la la la la la la la la
You make me wana la la, la la la la
