A professor was talking about rules on the university campus.
“The female dormitory will be out-of-bounds for all male students, so too the male dormitory for 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, a male student in the crowd inquires, “Er… How much for a season pass?”
