Overheard: a one-person, two-shoe dialogue

While we were in the car, driving to daycare, this morning, I overheard something along these lines from the back seat:

Ordinary Zeke voice: Hello, I am a shoe.
High-pitched, squeaky Zeke voice: Hello, I am a shoe, too.
Ordinary voice: Hello, shoe, we are friends. Let's dance!

He proceeded to wiggle his feet.
