two white dots

The young kindergarten teacher had just instructed her students to come forward as their names were called and be prepared to draw something on the blackboard that had been the cause of excitement in their homes during the previous week.

One by one the pupils came forward and sketched such items as report cards, television sets, mothers' new hats, and the like. When it came time for Johnny, the class cutup, to comply with the assignment, however, he walked to the board and simply made two white dots before returning to his seat.

Suspecting that he was up to one of his usual pranks, the teacher advised Johnny that he had better he able to explain why those two dots were exciting if he didn't want to be kept after school.

"Well," said Johnny, "the other day you told us that those dots are also
called periods-" "That's correct," the teacher interrupted. "But what could possibly be exciting about two periods?"

"Beats me," replied Johnny. "But that's how many my older sister says she's missed, and it's causing an awful lot of excitement around our house!"
