A kindergarten class had a homework assignment to find out 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 called upon walked up to the
front of the class, and with a piece of chalk, 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?" "Darned 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."
