Why do all girls think they're fat

There's a little girl on my mind
All the time there's always one
Look what shes done...
She makes me look at her thighs
You know I sure hate to lie
But what can I tell her
You know it's so beautiful
Man how come all girls think there fat?
Hey hey hey she's so pretty my friend
Hey hey hey I feel stupid... again
She said "It's all right, come over tonight,
My mom's not home, I'm all alone!"
She took me back to her house
She pushed me down on the couch, she said
"Now it's all right, were gonna be good friends
Cause that kissin' only leads to the end"
Hey hey hey she's so pretty, my friend
Hey hey hey I feel stupid
