What would I do without you?

After tonight's bath, Thing One squirted the water out of all the bath toys, put them in their proper bin and called me in to tell me he was ready for me to get his towel for him.
Me: You're such a good helper. Thank you for helping me. I don't know what I'd do without you.
Thing One: I don't know what I'd do without YOU. Because I can't drive, and I can't make food.

You are unwise

Thing Two likes to pretend he's Darth Vader when he calls out to Luke with increasing volume, "You are unwise to lower your defenses!" It comes out more like:

"Yah weh yah weh YAH WEH!"

Singing

Thing Two likes to sing, even though the words escape him. He sings the alphabet song with the good pitch:

"A B D B D B D. D B D B D B D ..."

The orchestral theme from The Phantom Menace (the one where Darth Maul fights with his lightsaber):

"Ha ba da. Ha ba da. Ha ba da. Ha ba da."

Most recently, Baa Baa Black Sheep. And of course the Imperial March and the Star Wars theme, sung in "dun"s.
