 Brak s parents notice an ad in the newspaper telling them that Fish Buckets, a restaurant that serves seafood, is having a special event, a "Salute to Crabs" and Brak s parents decide to make a night of it by going out and eating seafood, but Brak and Zorak can t come with them because they didn t do their homework. In a quandary, Brak wonders what must be done and so Zorak sets forth the idea that they can go back in time and convince their past selves to do the homework so as not to be faced with the stuff later. This doesn t work, as the past selves only go back in time and play video games with Zorak and Brak, on and on down the line, as the duo decides to keep going back in time to make their past selves do the homework, more and more past selves keep coming back. Faced with this mistake, Zorak and Brak decide to go back in time to stop homework from ever being invented. They make it, and meet up with two wizards from that era who invent homework. Zorak convinces them not to invent it, and the duo goes back to their own time era only to realize that some of the things that they do and act out are gone.
