Poker Face. It's something about the way the beat bursts in after the last "Muh Muh Muh Muh" at the beginning. & for some reason, the "P P P Poker Face" that plays for like 45 seconds @ the end of the song always gets me off my ass for some reason. I don't know why though cuz i can listen to the "P P P Poker Face" in between the verses and just sing along but when that end comes on,bitch it's like im at a damn concert.
