Episode #205 "Hotel Dick"

  The Solomons attend a science-fiction film and are angered by what they consider to be an unrealistic depiction of aliens. Dick is particularly concerned about what Mary will think if she sees the film and decides that maybe it's time to reveal his true identity to her. When Tommy and Harry tell Dick about a sci-fi convention being held in Cleveland, Dick decides it's the perfect place to break the news to Mary, and he tells everyone they're going on a road trip. At the convention, Harry has no luck convincing anyone that aliens really are attractive people. Back at the hotel, Dick fumbles his attempt to reveal himself to Mary, while Sally, Harry and Tommy master all the fine points of ordering room service, valet service, massages in their room and the adult movie channel and leave George Takei of Star Trek, who's appearing at the convention, stuck with the bill.
