Reasons not to mess with children.

A little girl was talking to her teacher about whales.
The teacher said it was physically impossible for a whale to swallow a human because even though it was a very large mammal its throat was very small.
The little girl stated that Jonah (in bible) was swallowed by a whale.
Irritated, the teacher reiterated that a whale could not swallow a
human; it was physically impossible.
The little girl said, "When I get to heaven I will ask Jonah".
The teacher asked, "What if Jonah went to hell?"

The little girl replied, "Then you ask him".
