Frank, a former student of Mary's, returns for a lecture series, making Dick jealous, and paranoid that he is after her. When confronting Frank, however, he hints that he is gay, but Dick misreads him and is convinced that he is hinting at being an alien. Therefore, Dick begins to regularly accompany Frank to Geoffrey's Lounge, which he thinks is an alien bar. Meanwhile, Sally, Harry and Tommy receive a visit from Don, who has just inadvertently foiled a bank robbery, and decide to use their superior knowledge to rob a bank themselves. As the episode progresses, each of the Solomons dons a costume of one of the Village People (Dick as the construction worker, Harry as the indian, etc). At the end of the episode on their porch roof get-together, they are joined by Don in his police uniform to complete the tableau, and the episode ends to a Village People song.

After hearing the crowd sing The Star Spangled Banner at a baseball game, Dick realizes that humans are passionate about their country of origin and attempts to become more American, only to discover that he actually has a Canadian passport. Meanwhile, the other Solomons' work on the basis that all Americans are equal, and start an equality system in the house, putting Harry in charge, who makes everybody wear the same uniform and rations household items, until Tommy begins to fear that they are losing their individuality.

With the identity of Scoochie revealed to be Liam Neesam, who had visited Pendelton three years ago, Dick is panicked, and follows Liam and Mary to dinner, where he overhears Liam offering her a job with a six-figure salary. The other Solomons suggest that Dick reveal himself as another alien in order to gain Liam's respect. When he does, however, Liam reveals that he doesn't care for Mary, but that she is part of a huge plan to transform the Earth's entire population into monkeys, and rename it Planet Monkey World, so that it may be an exhibit for aliens. Meanwhile, Sally, Harry and Tommy discover that their favorite movie, Arthur 2: On the Rocks' has a 'prequel' - Arthur.
