Lyrics
Here we are! Face to face
My future self n' me!
Stan: Stop it
So much alike, and yet so different
Stan: No
One of them's messy, the other ones clean!
Getting along isn't always easy
Sometimes we disagree
Stan: Quit it.
But in the end, where good for each other!
Some peas in a pod
Future self n' me
Future self n' me
Future self n' me
