I'm busy talkin' to this guy. When I see outta the corner of my eye.... Look who's here how you doin'.. Why don't you tell me who let you in?. [Chorus]. We don't care if you think our party's cool. 'Cause we do!. And we don't care if you had more fun in Sunday School. 'Cause who invited you? Who invited you?. Who invited you?. What do I have to do to get rid of you? Who invited you?. You say you're everyone's best friend. But last night you made fun of all them. You never told me not to tell.... You trusted me but you don't know me that well!. (Chorus). We don't care if you think our party's cool. 'Cause we do!. And we don't care if you had more fun in Sunday School. 'Cause who invited you? Who invited you?. Who invited you?. What do I have to do to get rid of you?. Who invited you?. Who invited you?. Who invited you?. What do I have to do to get rid of you?. Who invited you?. Face it dude you can't beat me. In your Charlie Brown shirt and Cavariccis.. Baby you come up to my waist. You need a barstool to get up in my face.... (Chorus). We don't care if you think our party's cool. 'Cause we do!. And we don't care if you had more fun in Sunday School. 'Cause who invited you? Who invited you?. Who invited you?. What do I have to do to get rid of you?. Who invited you?. Who invited you?. Who invited you?. What do I have to do to get rid of you?. Who invited you?
