Les Liaisons Dickereuses 3rd Rock from the Sun : Season 6 Episode 1

Mary's wealthy sister Renata Albright has donated a large sum of money to have an extension built onto Pendelton University, but Mary knows that it is in fact a spiteful gesture designed to quite literally block the sunlight into her office. To retaliate, Dick schemes with Mary that he will woo Renata, win her, and then break her heart. Meanwhile, Sally and Harry are given ten thousand dollars by Renata to convert their house into a teen center.
