Four high school boys afflicted with spring fever skipped morning classes.
When they arrived at the school some time after lunch period, they reported to the teacher that they had a flat tire on the way to school.
Much to their relief, she smiled and said, “Well, you missed a test today.” But then she said, “Take seats apart from one another and get out a piece of paper and a pencil.”
Still smiling, she waited for the boys to sit down, then she said,
“First question, which tire was flat?”
