Dr. Pants: Music
Doppelganger Rock
I was standing in line for a ride at Disneyworld, when it suddenly occurred to me that there seem to be a finite number of faces, or general face types, in the world...That realization eventually evolved into this song...
Doppelganger Rock 
HEY MAN, YOU LOOK JUST LIKE A GUY I USED TO KNOW
HEY MAN, HE LOOKED JUST LIKE YOU AND HIS NAME WAS JOE
DON'T YOU KNOW WE ALL LOOK LIKE SOMEONE ELSE, IT'S NOT A BIG NEW THING
THE WORLD IS A CIRCLE AND THERE'S YOUR TWIN STANDING THERE ACROSS THE RING BECAUSE
JOHNNY LOOKS LIKE FREDDY AND JENNY LOOKS LIKE MARY
IT'S A NATURAL EVENTUALITY
JOANIE LOOKS LIKE TONI AND ROBBIE LOOKS LIKE BOBBY
DO YOU KNOW SOMEONE WHO LOOKS LIKE ME?
'SCUSE ME MA'AM, YOU LOOK JUST LIKE A GIRL I USED TO DATE
'SCUSE ME MA'AM, IS IT POSSIBLE THAT YOU SOMEHOW RELATE
DON'T YOU KNOW WE ALL LOOK LIKE SOMEONE ELSE, IT DOESN'T MEAN I'M HER SISTER
IT DOESN'T GIVE YOU THE RIGHT TO BUG ME JUST BECAUSE YOU MIGHT HAVE KISSED HER
