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 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 ".

A teacher was giving a lesson on the circulation of the blood. Trying to make the matter clearer, she said, "Now, class, if I stood on my head, the blood, as you know, would run into it, and I would turn red in the face."

"Then why is it that while I am standing upright in the ordinary position the blood doesn't run into my feet?"
A little fellow shouted, "Cause your feet ain't empty."

The children were lined up in the cafeteria of a Catholic elementary school for lunch. At the head of the table was a large pile of apples. The nun made a note, and posted on the apple tray:
"Take only ONE. God is watching."
Moving further along the lunch line, at the other end of the table was a large pile of chocolate chip cookies.
A child had written a note,
"Take all you want. God is watching the apples.
