3rd Rock from the Sun (1996) : 4x14

When a meeting is rescheduled without her having been notified, Mary begins to have doubts about the longevity of her position as Dean, and Dick leads her to become paranoid that there is a conspiracy to have her removed from her job. The pair decide to investigate, and end up breaking into Judith's office by night for evidence, only to be caught by the police. Vicki Dubcek decides that the best thing Sally needs to help her get over her break up with Don is a weekend of riverboat gambling on the Cincinnati Queen, a floating casino - where Harry manages to win big, while Sally gets her lips on a Neil Diamond impersonator.
