The 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
for the little kids to give their reports, the
teacher was calling on them one at a time.
Eventually little Johnny's turn came. Little
Johnny walked up to the front of the class, and
with a piece of chalk, made a small white dot
on the blackboard, then sat back down.
Well the teacher couldn't figure out what Johnny
had in mind for his report, so she asked him
just what that was.
"It's a period," reported Johnny.
"Well I can see that," she said, "but what
is so exciting about a period."
"Damned if I know," said Johnny, "but this
morning my sister said she missed one. Then Daddy
had a heart attack, Mommy fainted, and the man
next door shot himself."
