Where do they come up with this stuff?

Okay so today I drove "Little Miss" and myself home from Dad's work. We just finished washing my car and were on our way to get her a courtesy cone at Arctic Circle. Out of nowhere, she asks, "do frogs have teeth?"

In my infinite wisdom, I answer "I don't know". I hoped that would end it.

Not five minutes later, she asks it once again. This time I thought about it and answered, "I think they have long tongues to help them catch and swallow flies."

After getting the icecream, we are pulling into the driveway to our home. She asks, "Do ants go potty?" I said, "I guess so." She responds by asking, "How do ants go potty?" I answered by saying "like dogs, I guess."

Seriously, what goes through the heads of four year olds? Well, today I got somewhat of an idea.
