051 - Party Pooper Pants

Patchy organizes a house party, and all the guests come except for SpongeBob himself, who can't understand what's written on the invitation because it was destroyed by the water. So they throw it in fire. Potty invites The Birdbrains, a band consisting of birds. Patchy attempts to remedy the music situation by performing his own (horrible) song, and Potty tells Patchy that it's time for his flute solo. Patchy starts playing, but soon realizes that he plays a fife, not a flute, and that the "flute" is actually dynamite. It explodes, leaving only his head intact. The Birdbrains then have the opportunity to play music, singing "Underwater Sun." After they finish, Patchy returns to end the show, with a barrel for a body being kissed by girl parrots.

While shopping at the Barg 'N-Mart, SpongeBob finds a "Plan Your Own Party Kit," and decides to throw a party using the kit. Despite the kit advising to invite "only your closest friends", SpongeBob invites nearly everyone in Bikini Bottom. When all his guests arrive and start partying, SpongeBob stops them from doing what they want and forces them to follow a very elaborate and specific schedule of events that he planned. These include discussion cards and reading newspaper comics to his guests. SpongeBob accidentally locks himself out of his house because he got the wrong newspaper, allowing the guests to have fun. After continually trying to get into his house using different methods, he grabs a pickax and attempts to break in while dressed as a bunny. The police find him and place him under arrest, but when SpongeBob explains everything, they don't arrest him. However, the police attempts to make him miss the party by arresting him for not inviting them. When he gets back, he is depressed because his party failed, until Patrick comes and tells him that it was the greatest party all of them has ever been to, and that he should do exactly the same thing next weekend. SpongeBob smiles gladly and becomes proud and finds Gary wearing a lamp. The episode ends as SpongeBob turns off the lamp.
