A kindergarten class had a homework assignment to find out about something exciting around their home or nearby places and relate it to the class the next day.
The next day, after the routine songs and rhymes they normally practice, the pretty teacher wanted to know from the kids, some innocent excitement that they witnessed around them.
When the time came to present what they'd found, the first little boy Jim, 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
“Jim, what is that?”
"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."
