well after you read this you will never hear this song the same way again, I to really loved this song when it first came out,but if you listen very closely to the second part of the chorus:
P-p-p-poker face, p-p-poker face
(Mum mum mum mah)
P-p-p-poker face, p-p-poker face
(Mum mum mum mah)
she's not saying" p-p-poker face"
it sounds like...." p-p-fu@ker face"
