The 5th birthday of Michelle Tanner (played by the Olsen twins) sparks a retrospective of the family's previous adventures, conveyed via excerpts from the series' first four seasons. But Michelle is in anything but a festive mood: with Becky about to give birth to twins any day now, the youngest member of the Tanner household is worried that she'll soon be upstaged by her new cousins. This is the first episode of a two-part story.
