Where has Humpty gone?

On the way to school this morning, Cooper looked at one of the buildings that has a retaining wall at the street level.

He said, "Eh, there's Humpty Dumpty's wall."

I replied, "It is?"

Cooper, "Where's Humpty Dumpty?"

"I don't know. Where do you think he is?"

Cooper, "Maybe home.  I miss Humpty Dumpty."

Where does he get this stuff?

At least he has an active, if not quirky imagination.
