On the first day of college,
the Dean addressed the students, pointing out some of the rules.
"The female dormitory will be out-of- bounds for all male students,
and the male dormitory to the female students. Anybody caught breaking
this rule will be fined $20 the first time. Anybody caught breaking
this rule the second time will be fined $60. Being caught a third
time will incur a hefty fine of $180. Are there any questions?"
At this point, a male student in the crowd inquired, "How
much for a season pass?"
