(Spoken:)
She went away
And you hung around and bothered me every night
And, when I wouldn't go out with you
You said things that weren't very nice

My girlfriend's back, and you're gonna be in trouble
(Hey la, hey la, my girlfriend's back)
When you see her comin', better cut on the double
(Hey la, hey la, my girlfriend's back)
You've been spreadin' lies that I was untrue
(Hey la, hey la, my girlfriend's back)
So look out now, 'cause she's comin' after you
(Hey la, hey la, my girlfriend's back)

Hey, she knows that you've been tryin'
And she knows that you've been lyin'

She's been gone for such a long time
(Hey la, hey la, my girlfriend's back)
Now, she's back, and things will be fine
(Hey la, hey la, my girlfriend's back)
You're gonna be sorry you were ever born
(Hey la, hey la, my girlfriend's back)
'Cause she's kind of sweet, and she's very cute
(Hey la, hey la, my girlfriend's back)

Hey, she knows I wasn't cheatin'
Now, you're gonna get a beatin'
What made you think she'd believe all your lies?
You're a pretty girl now, but she'll be cuter than you
Wait and see!

My girlfriend's back; she's gonna save my reputation
(Hey la, hey la, my girlfriend's back)
If I were you, I'd take a permanent vacation
(Hey la, hey la, my girlfriend's back)

Hey, I can see her comin'
Now, you better start a-runnin'

*instrumental*

Wait and see!

My girlfriend's back; she's gonna save my reputation
La, hey la, my girlfriend's back
La, hey la, my girlfriend's back
