On the first day of University, the Dean addressed the students, pointing out some of the rules: “The female Halls will be out-of-bounds for all male students, and the male Halls to the female students. Anybody caught breaking this rule will be fined twenty pounds the first time.”
He continued, “Anybody caught breaking this rule the second time will be fined sixty pounds. Being caught a third time will cost you a fine of one hundred and eighty pounds. Are there any questions?”
A male student in the crowd inquired: “How much for a season pass?”
