Determined to get even with snooty landlord John Hill (Keene Curtis) once and for all, Sam (Ted Danson) pulls out his secret weapon of mass destruction by unleashing Carla (Rhea Perlman) on the hapless Hill. Things don't work out quite as planned, however, when Carla falls in love with the shiny-domed landlord. Meanwhile, Cliff (John Ratzenberger, who also directed this episode) tries to overcome his fear of four-legged locomotion. ~ Hal Erickson, Rovi
