Unsong

I fold the shirt
B: I unfold the shirt
A: I lace the shoes
B: I unlace the shoes
A: I stack the clothes
B: And I unstack them
A: I pack the clothes

And I unpack them
It should be clear to anyone:
Anything you can do --- I can un.

A (spoken): Why, that's the most unheard of thing I ever heard of!
B (spoken): I think you're getting the idea.

A: I wrap the box
B: I unwrap the box
A: I tie the string
B: I untie the string
A: (trying to keep B away) I lock the door (between them)
B: And I unlock it
A: I block the door

And I unblock it
Undoing things is lots of fun --
Anything you can do --- I can un.

A: I button my shirt
B: I unbutton your shirt (it falls off)
A: I buckle my belt
B: I unbuckle your belt (pants fall down)
A: (getting angry) I dress again

Well, just to impress you
I undress you. (A's clothes fall off, down to underwear. A sneezes.)
Bless you!

A (spoken): Why, you unspeakable, unbelievable, unscrupulous, unmitigated....
B (spoken): "Don't forget "unfair"!"

A: I comb my hair
B: I uncomb your hair (it's a mess)
A: I blow my nose (blows)
B: I unblow your nose (A inhales)

Oh, yukk!
I make the bed
B: And I unmake it

(trying to stop B, falls on bed -- it collapses) Oops! I break the bed
B: And I unbreak it

(surprised that B has actually done something helpful) Why, thank you!
B: You're unwelcome -- it was unintentional

"Un" can undo whatever you've (I've) done
Anything you (I) can do, I (you) can un!
