The leader of an alien recon party on Earth discovers he has "feelings" for a professor.

While Dick is trapped in the basement, Evil Dick begins a plan to impregnate all women in Ohio.

Sally, Tommy and Harry return from the home planet with a surprise for Dick: a bride-to-be.

Randy "sells" Harry to a circus, where he achieves popularity as the act "Hargo the Alien". In order to try to find him, Tommy and Vicki visit a psychic, but it turns out that she's actually seen the Hargo act herself and so knows where Harry is. Meanwhile, the loss of Harry means that the aliens' annual status report cannot be sent, so the Big Giant Head punishes Dick for not submitting it by slowly shutting down his brain.

The Solomons are relieved when Vicki's baby turns out to be human, but horrified when she announces her plans to sell her story to the papers. When a reporter comes sniffing around, Sally gives Dick the title of Security Officer and orders him to kill him; however he can't, so she makes him High Commander and herself Security Officer so that she can kill the reporter herself. Dick then reminds Sally that he is now the High Commander, and that there is nothing she can do to reverse it.

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.
