Why?

Nicholas:  Who made poison ivy?

Me: God did.

Nicholas: Why?  And why did He make bad animals? Oh, I know, so they can have cool shows on Animal Planet.  But then, if there were no stingrays, we'd still have a Crocodile Hunter.  You know, if brains weren't made, I wouldn't be smart.  How'd I get so smart anyway?  Oh yeah, God.

Quite a conversation and I barely talked.
