what makes elementary school teachers laugh?

this, apparently!

"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 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". "
