"You Don't Know Sponge" is a SpongeBob SquarePants episode from season seven. In this episode, SpongeBob and Patrick take a quiz on each other, which threatens their friendship.



It starts out at the Krusty Krab where SpongeBob and Patrick are making their favorite noises, while simultaneously annoying Squidward. SpongeBob's is the dolphin laughing and Patrick's is the song of the great blue whale. Squidward, who is extremely annoyed at this point, asks them what was happening. They explain that they are doing stuff together out of a magazine called Simple-Ton. They then take a quiz to find out how much they know about each other and SpongeBob does fantastic. However, Patrick does terribly. Squidward then looks at the book and laughs because Patrick guessed that the shape of SpongeBob was a triangle.

Not Your Friend

"Looks like he really isn't your friend after all!"

Patrick buys two ice cream cones (but only gets Patrick's favorite flavor which is dill pickle swirl with mustard and extra bacon bits) and asks SpongeBob for money. SpongeBob becomes upset, and he tells Patrick that he doesn't know him anymore after tearfully throwing the money on the ground. He then runs off to his house crying and SpongeBob cries so much that he fills up Gary's food bowl.

Eventually, SpongeBob goes to Sandy for help and she says that they don't have to know everything about each other and they probably just need some time apart. SpongeBob then tries to avoid Patrick, but he sees him go to the gym and many other places with Larry. Patrick is shown with a gift when SpongeBob angrily confronts the two, followed with Larry uncomfortably backing away from them. Patrick then explains that Larry is not his best friend, Larry helped Patrick find a gift for SpongeBob and that he got the gift for SpongeBob, which was a pair of glasses with a fake nose and mustache.
