144b - Karate Star

SpongeBob is in his kitchen, karate-chopping a pineapple to look like Gary. He puts it on the floor, so Gary is eye-level with it. It attracts flies and one flies into SpongeBob's mouth and he begins to choke. Patrick walks in and asks for some cheese before realizing SpongeBob's choking. Once it becomes clear to him, he punches SpongeBob. SpongeBob flies across the room and lands against the wall and the fly leaves his mouth. He offers anything in return and gives Patrick the cheese.

Patrick decides that he wants to learn Karate. SpongeBob is skeptical but gives in since that was the deal. He tries to teach Patrick the "reverse whirlpool," and then to fly into a brick wall and destroy it. Patrick succeeds in this but ends up unable to stop flying and destroys a lemonade stand. Next, SpongeBob tries to teach Patrick a move where he spins around on one foot. Patrick then starts spinning uncontrollably. SpongeBob gives up, and Patrick perfectly karate-chops a cinder block in half out of anger. He chops a steel sword and a boat as practice and then almost chops Baby Rechid. SpongeBob stops and warns him not to chop any living organisms or their property. He reminds him that "with power comes responsibility," but has to go to work and leaves Patrick, who starts chopping everything from arcade games to spinach.

A man runs into the Krusty Krab screaming that there is a "mad chopper" on the loose, and SpongeBob, knowing the man is referring to Patrick, sets off to stop his friend. Meanwhile, Patrick is in an ice-cream shop. He is buying a cone stacked high with every flavor they have. He owes them over eighty dollars but tries to trade him for a lollipop. The ice cream man refuses and threatens to call the cops when Patrick chops the glass, cracking it, and tips the ice cream into his mouth while the ice cream man holds onto the money from the tip jar. The manager yells at the ice cream man for holding the money in the tip jar. Patrick gains considerable weight, and no longer fits through the door. He chops it, and exits. SpongeBob comes and tells Patrick to stop destroying Bikini Bottom, but by that time, Patrick's arm can't stop chopping. He eventually makes his way to the Barg'N-Mart and destroys the structure and crushes SpongeBob. He finds a pack of kitchen sponges, and believes that this is SpongeBob's carcass. He becomes very mad at himself and rips off his own hand. The real SpongeBob, who was trapped under a pile of rubble, wakes up and Patrick grows his hand back, swearing never to use karate again.

Patrick then badly rebuilds the Barg'N-Mart. Patrick is then shown karate chopping a shopping cart, leaving SpongeBob confused. Another Patrick then appears, and explains that in addition to sea stars being able to regenerate limbs, limbs are able to regenerate bodies. The two Patricks then laugh as the Barg'N-Mart gets destroyed, and the episode ends.
