[nilesfunnies] Fw: Period

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 the teacher called on walked up to the front of
the class, and with a piece of chalk, made a small white dot
on the blackboard before sitting back down.

Puzzled, the teacher asked him what it was.

"It's a period," he replied.

"I can see that," said the teacher, "but what is so exciting
about a period?"

"Darned if I know," he said, "but this morning my sister was
missing one. Mommy fainted, daddy had a heart attack and the
boy next door joined the Navy."
