116b - To SquarePants or Not to SquarePants

This episode starts with the narrator talking about a tragedy, and showing an over-water hurricane, and then showing footage of the 1940 collapse of Tacoma Narrows Bridge (Galloping Gertie), with a guy running from the bridge before its collapse. After that, it goes to a rainy day at SpongeBob's pineapple where SpongeBob is inside with the calendar on January 10. The narrator said that the tragedy happened three days ago; it then flips it back to January 7. SpongeBob is then doing chores, including laundry, with his pants and Gary's shell. Then Patrick calls SpongeBob to show that he can make funny sounds with his tongue for a very long time; SpongeBob asks Patrick if it can wait, but Patrick refuses, so he continues on. Meanwhile, Gary gets his shell out of the laundry. By the time SpongeBob gets to the laundry machine, his pants had shrunk. He goes to the store to buy new ones, but Patty Rechid declares that there will not be any SquarePants for months. He then looks through the pants, he tries many pairs but was not interested, but he then finds the pants he usually wears, except they are round, not square.

While walking with his round pants, SpongeBob bumps into Patrick, but Patrick does not recognize him. He bumps into Sandy, who pretends that she does not know SpongeBob saying that they must call him SpongeBob FancyPants. Then, SpongeBob passes Squidward's house, and Squidward pretends not to recognize SpongeBob in order to get him to leave him alone. Being gullible, SpongeBob really thinks that Patrick, Sandy, and Squidward do not know him, so he starts himself over, naming himself SpongeBob RoundPants.

SpongeBob gets his job at the Krusty Krab again, and looks to Squidward for pointers. Squidward gives SpongeBob his bad routine of being a Krusty Krab employee (including not throwing the trash in the dumpster, being rude to the customers, nasally laughing like Squidward, burning Krabby Patties, taking too long in the bathroom, and even sleeping on the job). Mr. Krabs realizes what is going on, and he does not joke around when he sees SpongeBob. SpongeBob then tells Mr. Krabs that he cannot be SpongeBob SquarePants again, as he has round pants. Mr. Krabs then suggests that he just remove them if that was the case. Then, SpongeBob takes off his pants, but Sandy calls him "SpongeBob UnderPants," and the episode ends with SpongeBob looking at his underwear and screaming with embarrassment.
