Penny has an odd hobby, she likes to bring home college boys who are out past their bedtime and punish them for their naughty ways. She finds the ones partying too hard to remember how they got to her apartment tied up and naked! When her latest victim wakes up he is in a strange bed wearing nothing but his underwear and a cartoon mouse ears hat she ignores his questions and tells him what happens to bad boys up late doing things they shouldn't...They get put back in diapers!
