3rd Rock from the Sun - Season 6 - Eps 12: Dick's Ark
Dick has bought a new camera, with which he makes Mary angry, by constantly taking her picture against her wishes. As a result, Mary decides that the two need some time apart. Meanwhile, Sally's coat is ruined when Harry wears it out in the rain, but he claims that the Channel 10 weatherman said it was going to be sunny. Sally marches down to the station and tries to convince them to pay for her coat, but it soon becomes apparent that Sally is excellent at predicting the weather, so they give her the position. Dick, however, is worried that Sally's spot on prediction of the weather will attract unwanted attention and so, when she discovers that Rutherford is to be hit by tornados, he orders her to report otherwise.
