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.
There is dual girl trouble in the O'Hara household. George, the dog who Tim is looking after for Mr. Burns, is in love with Chloe, the dog from next door. Through trying to get George and Chloe together, Tim falls for Chloe's owner, Marsha Carson. However Marsha has had some recent relationship problems of her own. Howard Loomis, her boyfriend, took off to Mexico without as much as a goodbye. Because Marsha feels betrayed by Howard, she is now overprotective of Chloe and suspicious of all men, including Tim. Tim's case is not helped by Angela, who bad mouths Tim to Marsha solely because Angela has a crush on Tim herself. From information from Chloe, Martin finds out the whereabouts of Howard, who rushes back to Los Angeles based on "anonymous" information provided by Martin. Howard, whose departure to Mexico was beyond his control and who tried to contact Marsha prior to his departure, clears the air with her and reignites their relationship to the point of getting engaged. This leaves Tim out in the cold. But at least all works out for George and Chloe, as Tim is given the task of sitting for Chloe while Marsha and Howard rush off to Las Vegas to get married.
