Mary Mary - Identical Twins

Hello!
We're twins, we're twins, yes sir
I am me she is she
Except when I pretend I'm her

And when we switch
You can't tell which is which
You don't know who you're talking to
Because we're identical, 'dentical, 'dentical, identical twins!

We look a lot alike
But we are not alike
I'm loud!...I'm quiet
She's serious...she's a riot
We're totally, totally
Different, different
Identical twins!
