Squidward goes into the freezer looking for something, but accidentally breaks the knob. Thinking that somebody will notice he is in there, he doesn't panic-- but freezes in there. Never noticed, he winds up in the future and is not too thrilled about the way the new stuff works. So the octopus goes into a time machine and finds two prehistoric people (later named SpongeGar and Patar) and accidentally invents jellyfishing. When he gets back, he ends up being the idiot who created jellyfishing. Squidward then goes back to his everyday routine.
SpongeBob and Sandy are diligently practicing Karate, but Mr. Krabs forbides it as SpongeBob thinks Sandy is in disguise and begins attacking his customers. Sandy begins to attack him, but SpongeBob doesn't fight back as he doesn't want to get fired. However, Mr. Krabs sees it and still fires SpongeBob. Sandy eventually convinces Mr. Krabs not fire SpongeBob, but warns him that next time he won't be quite as easy. However, at a picnic in the park, they are tempted to fight and they finally do... in front of Mr. Krabs! However, instead of firing him, he hires them both to help make quick Krabby Patties.
