SpongeBob LongPants

Spongebob Longpants is an episode of SpongeBob SquarePants.

Plot
On a cold day, the Salesfish sells SpongeBob a pair of long squarepants. He goes to the Krusty Krab to show them off and Mr. Krabs promotes him to cashier, making Squidward work the grill, pointing out that he doesn't even have any pants. However, SpongeBob keeps annoying Squidward with lots of questions until Mr. Krabs decides to give SpongeBob a different job in which he walks around and talks to the customers. Eventually, SpongeBob gets a tiny drop of ketchup on his pants leg, so he resigns. After paying for a couple's bill and getting his pants dry-cleaned, SpongeBob manages to get his driver's license because of his new pants, which causes Mrs. Puff to wake up in fear. SpongeBob is invited to a party by some upper-class people. At the party, SpongeBob asks where the party hats and clowns are, and suggests everyone go to the new Mermaid Man and Barnacle Boy movie, but they end up seeing an art film called The Table instead, which is just a shot of a table that needs cleaning with random noises playing in the background. SpongeBob meets his friends outside, who are going to see the Mermaid Man movie, but SpongeBob isn't allowed in because of his pants. SpongeBob tries to get the pants off in desperation with a parking meter, but only succeeds in blowing up a car. Mr. Krabs comes out and cuts SpongeBob's pant legs off (and SpongeBob's legs, but being a sponge, his legs grow back). The driving instructor comes by, sees SpongeBob's short pants, and revokes his license (which causes Mrs. Puff who was on high-alert to calm down), but SpongeBob doesn't care and enjoys the movie.
