"Girls Don't Have..."

The following is a direct quote from the little guy as he was going potty one day. We have the wierdest conversations while he's going potty. "Girls don't have a nozzle. Only boys have a nozzle. You don't have a nozzle. Where'd your nozzle go? Did you lose it? You gotta get one back. Maybe just a little one so you can go potty. Then you need a bandaid."

He is getting so curious about everything in the world. Daddy was trying to teach him that only boys have the nozzle, but he was very confused. He asked him how Mommy went potty if she doesn't have a nozzle. How far to divulge down this road at such an age...?

ps- he doesn't really say nozzle...
