[Chorus]
Who was that? Who was that?
Someone walked their feet through my house
Who was that? Who was that?
Someone's sneakin' quiet as a mouse
Who was that? Who was that? (Who was that?)
Someone left their shoes on the stairs
Who was that? Who was that?
Laughin' just like no one cares

[Refrain]
Someone's in my house, I declare
Playin' cards, solitaire (Who was playin' in my house?)
Someone's in my kitchen munchin' out
Peanut butter, there's no doubt (Who was eating in my house?)
Someone took a bath, Mr. Bubble
Middle name must be trouble (Who was playin' in my house?)
Someone's on the porch, right outside
Here I come, you better hide (Who was hiding inside?)

[Chorus]
Who was that?
Someone walked their feet through my house
Who was that? Who was that?
Someone's sneakin' quiet as a mouse
Who was that? Who was that? (Who was that?)
Someone left the radio on
Who was that? Who was that?
One minute here, now he's gone
[Break]
Who is it? Who is it?
What!?

[Refrain]
Someone's in my house, I declare
Playin' cards, solitaire (Who was playin' in my house?)
Someone's in my kitchen munchin' out
Peanut butter, there's no doubt (Who was eating in my house?)
Someone took a bath, Mr. Bubble
Middle name must be trouble (Who was playin' in my house?)
Someone's on the porch, right outside
Here I come, you better hide (Who was hiding inside?)

[Outro]
Ba-ba-ba-ba-ba-ba-ba-ba, ba-ba-ba
Ey, hey, yeah-yeah
Ba-ba-ba-ba-ba-ba-ba-ba, ba-ba-ba
Ey (Hey, hey)
Who was that? Who was that? Yeah, oh
Who was that? Ba-ba-ba-ba, hey
Who is it? Who is it?
