Chipettes:

Hey boys, just what was that noise
Comin from over there?
If it wasn't you and it wasn't me
Then what in the wide wide world could it be?

You want to scream and shout
and jump right out of your feet
Don't be cryin' about
Come on and take my hand and you will understand
Everything's gonna be alright
Don't you be afraid when things go bump in the night
Get closer to me and baby hold on tight
Cause everything's gonna be all right

Chipmunks:

Hey girl, we don't wanna rock your world
But we don't believe in that mean old boogie man
There ain't no such thing no how, no way, where
But sometimes late at night we still get a little scared

You want to scream and shout
and jump right out of your feet
Don't be cryin' about
Come on and take my hand and you will understand
Everything's gonna be alright
Don't you be afraid when things go bump in the night
Get closer to me and baby hold on tight
Cause everything's gonna be all right

(Repeat till fade)
