Engine and Caboose

Nate was getting dressed this morning and he said, "mommy, I have a penis and a butt."

"Well, yes you do...isn't that great?" confirming how wonderful his body is.

"Yep" he said. "This is the engine, (pointing to his front), and this is the caboose." (pointing to the rear)

I couldn't have said it better myself. :)
