On the first day of college, the Dean gave a speech about on-campus 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, $60 the second time, and $180 the third time. Are there any questions?”

At this point, a male student in the crowd raised his hand, “How much for a season pass?”
