Lyrics:

Who walks in when I walk out?
Who gives you that 'hi baby'
Who's it, who, got me jealous of you.
Who walks in when I walk out?
Now don't you know youre my baby,
who's it, who, got me worrying too?

Well, when we kiss, I kinda miss
something that used to be.
Everyday, while I'm away, I get a feeling
that you're fooling me.

Who walks in when I walk out?
Who gives you that 'hi baby'
who's it, who, got me jealous of you?
