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. She was reluctant to call upon little Johnny, knowing that he
sometimes could be a bit crude. But eventually his 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 on something exciting, 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."
