At the museum, Martin discovers that the long-time curator, Wilbur Canfield, is very unhappy. He has just acquired a new expensive Egyptian piece for the museum, but the museum's board is questioning the authenticity and therefore merit of this acquisition. Because of this, Canfield himself is now questioning his own abilities, as he feels he may be getting too old to do his work properly. The board is calling in an independent expert, Pietro Donati. What's worse, Canfield once discredited Donati's evaluation. Martin will know the piece's authenticity, if he can only get a look at it. In doing so, Tim can get an exclusive story and Martin can validate Canfield as an expert in the field. But the artifact is stashed away behind security until Donati's arrival. Since Martin can't get close to it, he decides instead to levitate it to him. After Martin finds that it is indeed authentic, he has to get it back to the museum. However security is aware that it's missing and thus the museum is secured even more than usual while they try to locate the artifact. After some tricky maneuvering, Martin does manage to get it back into place, although to the bewilderment of security. However, Martin forgot to check for the mark of Ra, which definitely identifies the artifact as authentic. When Donati arrives to inspect the piece, he deems it to be a fake since the mark of Ra is not there. However Martin tells him to look a little more closely under the couple thousand years of residue. The mark is indeed there. Therefore it ends well for Canfield and Donati. The only person with an unhappy ending is Tim - his exclusive story was so good, Mr. Burns appoints him editor of culture, which is not exactly his cup of tea.

The Inter-Galaxy Corporation is launching a rocket to either Mars or Venus. Martin needs to convince them to choose Mars, so that he can stowaway and get home. J.M. Buckley, Inter-Galaxy's President, is an indecisive man, but is highly superstitious and makes many decisions on these superstitions. He is leaning toward sending the rocket to Mars, but two things are distracting him from making the announcement of such: it's Friday the 13th, and he's missing his lucky rabbit's foot. Martin overcomes the date superstition by making Buckley think that Friday the 13th is the luckiest day on the calendar. The missing rabbit's foot on the other hand Martin and Tim need to find. They locate it, but in cat-chewed state. Martin realizes that many rabbit's feet look similar and he uses his powers to recreate it to its original visual state. That's all Buckley needs to make the announcement to send the rocket to Mars, the launch to take place in two days. To thank the corporation, Martin suggests adding a magnetic oscilloscope, an invaluable piece of equipment for the mission, to the rocket. This act of kindness on Martin's part is also his error: with the addition of the oscilloscope, there is no more room for a stowaway.

Since Tim is unavailable for an outing, Martin asks Mrs. Brown out on a "date". Mrs. Brown herself can't make it since surprisingly she already has a date for that evening. Martin feels dejected, but he doesn't know why. Tim lets him know that he is jealous of Mrs. Brown's new suitor, Andre Philippe Charles Dupre, a suave, debonair fashion designer. On first glance, Martin must admit that Andre is a charming and accomplished gentlemen, worthy of Mrs. Brown's affections. But Martin digs a little deeper in hopes of finding fault with Andre. When Martin finds nothing, he feels ashamed about his selfishness, and vows to further the happiness of Mrs. Brown, a person for who he has deep affection, by doing whatever he can to foster her relationship with Andre. Martin does this despite gleaning from reading her mind that Mrs. Brown does not find Andre to be as romantic a suitor as she had hoped. Thus while Mrs. Brown and Andre are on a dinner date, Martin does whatever he can to make Andre appear the most romantic of suitors. Andre proposes, but Mrs. Brown turns him down and decides not to see him again. She felt the evening was too perfect and thus their relationship would have no where to go. She mentions to Tim and Martin that women prefer men with a few imperfections, she implying that Martin is that man for her.

Martin needs to electrically charge himself for his trip back to Mars. However he overcharges himself. He needs to rid himself of the excess electricity, and when he initially tries to discharge it, he blacks out half of Los Angeles. Martin is facing two problems. First, if he is overcharged for an extended period of time, he will exhibit unusual symptoms such as a plaid designed face. A current symptom is his continual sneezing which is causing electrical switches to turn on. And second, the power company is narrowing the source of the blackout to the O'Hara's neighborhood, and have called in the police to investigate the malicious tampering with the power grid. Martin figures the best course of action to discharge the electricity in a hurry is to do it direct at the source: the power house. In his invisible state, Martin hitches ride in the power truck that's come to investigate their neighborhood. After distracting the power man on duty, Martin manages to discharge his excess electricity safely back into the system. But once again, he's missed his opportunity to get back to Mars.

Martin convinces Tim to use his connections as a reporter to get Martin a tryout as the astronaut for a Mars destined rocket, privately financed by Omar M. Keck. Despite a slew of younger stereotypical astronaut types vying for the job, Martin's obvious advantages as a Martian get him the job. Before Martin is ready to leave, he allows Tim to prepare a story of his uncle "The Martian" for publication after Martin is on his way. On his way to the air force base with Martin, Tim leaves the tape of the story on Mr. Burns' desk - based on his usual schedule, Mr. Burns should arrive at the office after Martin and the rocket are safely in space. However the launch of the rocket is delayed, leaving Tim and Martin to rush back to the office to retrieve the tape. They rush back to base to watch the launch happen without Martin in the rocket. At least the launch was picture perfect!
