Little Johnny gets to school, only to have the teacher tell everyone I want you to come to the blackboard one at a time, and with just one sentence, describe the most excitement you have seen.
Others walk to the board and write about vacations, trips, Christmas, etc.
Finally it is Little Johnny's turn. He walks to the board, erases it, then puts a simple period (.) on the board. Teacher says "johnny, where is the rest of your sentence?"
He replies "that is it."
Teacher asked "how is that exciting".
Little Johnny said "My sister missed two of those and all hell broke loose at my house!"
