My-my-my poker face, my butt-f***er face

The story:

I was riding in the car with my family and had, since a year before believe that the lyrics I heard were the right ones. Since I don't spontaneously sing at home, nobody had ever told me otherwise. Poker Face comes on the radio and in the car the rules are different. We get to the part and everyone stops. That's when I decided to google the lyrics. I just assumed they were real knowing how much of a freak Lady Gaga is.
