A kindergarten class had a homework assignment to find out about
something
exciting and relate it to the class the next day. When the time came to
present what they'd found, the first little boy walked up to the front
of the class made a small white dot on the blackboard and sat back down.
Puzzled, the teacher asked him just what it was. "It's a period," said
the little boy.
"Well, I can see that," she said, "but what is so exciting about a
period?"
"Damned if I know," said the little boy, "but this morning my sister was
missing one, Daddy had a heart attack, Mommy fainted, and the man next
door shot himself."
