I was expelled from Sunday School. The interchange happened like this:

Teacher: And when God parted the waters and Moses led the People of Israel across the Red Sea...

Me: (Hand up)

Teacher: Yes wiz?

Me: How do we know that? I mean, how do we know that God parted the waters and all these people walked across on dry land?

Teacher: Well, because it's in the Bible. We're reading it right now!

Me: Yes, but how do we know the Bible is true?

Teacher: Well, because God wrote it!

Me: Well, if I wanted to write a book that I wanted people to pay attention to, wouldn't it be a good idea to say that God wrote my book as well? Just 'cause I say it's from God doesn't mean it is.

Teacher: [silence, then an attempt to move back to the story for the rest of the class]

And when it was all over, the teacher and pastor were talking to my parents. The rest as they say is history.
