Spongebob Squarepants is a television series that has been airing since 1999. It is currently airing its 10th and 11th seasons, with episodes from both seasons yet to air. The show holds the title of being the longest running original Nickelodeon program, and also holds the most episodes of any at 217. It is about the adventures of Spongebob Squarepants, a fry cook at the ever popular Krusty Krab. Spongebob is also an avid jellyfisher and bubble blower, who is noted for carrying a youthful spirit. Spongebob's best friend Patrick Star is a pink starfish who shares many of the same interests as the yellow sponge. Patrick is heavily noted for his clever brand of stupidity, a common point of humor in the show. Sandy Cheeks is another one of Spongebob's close acquaintances. She is a noted scientist, loves to practice karate, and houses a number of exotic pets. Mr. Krabs is Spongebob's cheap, yet noble, boss at the Krusty Krab. He is a red crab, noted for his time in the Navy and as a pirate. Squidward Tentacles is Spongebob's next-door neighbor and also is employed at the Krusty Krab. Heavily cultured in art and music, Squidward tries to express himself by doing self-painting and by playing his trusty clarinet. Unfortunately, Spongebob and Patrick can be annoying to his intricate work, so he is often presented as a villain in the series. Gary is Spongebob's pet snail and lives in Spongebob's House. Plankton is the main antagonist of the series and has devoted his life to attempting to steal the secret formula of the Krusty Krab's most popular entree: the Krabby Patty.
