Something Smells

"Something Smells" is a SpongeBob SquarePants episode from Season 2. In this episode, SpongeBob makes a sundae that gives him bad breath.

Plot
The episode opens up as SpongeBob wakes up one morning, realizing that it is Sunday, and decides to have an ice cream "sundae" for breakfast. However, he sees he has no ice cream and finds standard toppings like bananas and cherries to be blasé, so he instead creates a new type of sundae made from onions, ketchup, and the contents of a nearly dead potted peanut plant. Unbeknownst to SpongeBob, the result of eating the sundae is intense halitosis.

After breakfast, SpongeBob begins his Sunday to-do list, which consists of saying "Hi!" to everyone in town. Unfortunately, the townspeople are universally disgusted by the smell of SpongeBob's rancid breath and run away from him. SpongeBob is very confused by this, and asks Patrick if he notices anything wrong with him. Patrick, not having a nose, cannot discern the foul odor. After running down a list of possibilities, Patrick concludes that SpongeBob is simply ugly. SpongeBob is dismayed by this revelation and isolates himself in his home.

Later, Patrick visits SpongeBob, who has resigned to become a hermit. Patrick tells SpongeBob the story of The Ugly Barnacle, which fails to cheer him up. Patrick then encourages him to take pride in his ugliness. It works, and SpongeBob's confidence grows, so they decide to go see a movie at the Reef Cinema.

As they take their seats, all of the movie-goers still try to avoid SpongeBob, which angers Patrick and sends him into a tirade. Patrick forces the other viewers to look at SpongeBob. With every word SpongeBob speaks, the viewers panic and flee, soon leaving no one in the auditorium. Patrick gets hungry, so they go to the lobby to buy a snack. However, no one is at the counter. Instead, SpongeBob pulls some of his sundaes out of his pocket and gives them to Patrick. After eating them, Patrick feels a sudden urge to use the bathroom.

While washing his hands, Patrick asks a fish next to him for some soap, but he quickly runs away. Upon finding no one will stay within his vicinity, Patrick fears he has caught "the ugly" from SpongeBob and hides in a stall with a paper bag over his head.

Eventually, SpongeBob smells Patrick's extremely foul breath and tries to tell the rambling Patrick before shouting at him to get his attention. He then tells Patrick that it is not his appearance, but his breath which stinks, much to Patrick's relief. SpongeBob then asks what he ate, after being told it was the sundae SpongeBob made. The latter realizes that they are not ugly, but simply have bad breath from the sundae.

Immensely relieved their appearance was not the problem, the two begin to run around shouting, "We stink!", causing their noxious breath to melt down the theater. SpongeBob and Patrick run into Squidward, looking at wigs in a window display. SpongeBob cries out in joy, "Guess what, Squidward? We stink!" as they hug him, leaving Squidward staring blankly as SpongeBob and Patrick start running away laughing and cheering.
