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?
