Squidward gets home, and SpongeBob and Patrick are in Squidward's flowers. Patrick is upset when Squidward says he has no nose. Patrick picks up a hermit crab shell, thinking it is his nose but it then bites him. SpongeBob and Patrick are then walking around town where Patrick says all of his friends have noses. SpongeBob suggests he should have plastic surgery at Noses 'n Things.
After the surgery, Patrick uses machines to remove the bandages of his nose and smells perfume, pastries, Squidward's second purchase of flowers, and more good smells. However, he smells bad onion rings and a dumpster that chases him but when he gets home, he discovers how messy his house is. So, in 48 hours, Patrick cleans his rock up with a spray and a brush. SpongeBob and Squidward walk by, and Patrick smells more bad smells. He smells imported cheese, and puts a mask on to get it away.
Squidward tells him that it's supposed to smell like that. It then cuts to SpongeBob at his house lifting weights, when Patrick comes by and makes SpongeBob drop the weights. He plugs up SpongeBob's sweaty holes so no one will smell the sweat. Patrick then goes to the Krusty Krab, where he puts scented candles at each table and sprays the restaurant with air freshener. Mr. Krabs is angry about that because his customers are leaving. Patrick sprays Sandy with the freshener, causing Mr. Krabs to schedule a meeting with SpongeBob, Squidward, and Sandy at the Krusty Krab.
He says that Patrick's new nose is very troublesome. The guys think about torturing him, but SpongeBob says that it's not Patrick's fault. At first, they are confused, until SpongeBob explains that it's the new nose that's causing him to act like this, since his grandmother always tells him, "Punish the nose, not the man."
He suggests they should use a garbage ball so that his nose will shrink and fall off. The plan works, but Patrick is very sad because all he wanted was to smell like everyone else. They bury the nose, and SpongeBob is also sad. Squidward says he doesn't care one thing about the nose. He also says that pink moron will leave them alone and then Patrick says, "I heard that," with large ears.
Patrick also had a nose in "Don't Look Now," and even enjoyed having it get scratched by Squidward's fishing rod. He also had a nose that looked like Squidward's nose in "A Flea in Her Dome."
The Noses 'n Things shop that Patrick had his nose attached at, looks like a face. It has a nose on the front of the building.
The giant garbage ball on the title card and in the episode looks like Patrick's giant ball of gum from the episode "The Gift of Gum," but made of garbage instead of gum.
It is possible that Patrick's nose was damaged when he was removing the bandages and hence was more sensitive and why Patrick could not stand the bad smells.
The smells that bothered Patrick were:
Rotten onion rings
The smell of his house
SpongeBob's sweaty holes
The smell of the Krusty Krab
The garbage ball
The plot of this episode is almost similar to the Rocko's Modern Life (another Nickelodeon show and Stephen Hillenburg project) episode "Nothing to Sneeze At" where Bev Bighead gets amphibial blothal bloaticitis and gets a nose transplanted on and enjoys every smell but can't stand the smell of Ed. (Incidentally, that episode was co-written and directed by Mr. Lawrence).
The episode's title is a reference to the tongue-twister No nose knows snow like a snowman's nose knows.
Fred is first seen as a blue fish with a girl voice. When he appears in the Krusty Krab later on, he is a darker shade of blue with his manly voice. This was likely a voice cast error.
When Patrick sprays air freshener on Sandy underwater, she chokes, even though Sandy is wearing her helmet.
The Nickelodeon TV schedule calls this episode "Patrick Picks A Nose."
The wall of noses doesn't look like it could fit into the Nose-N-Things building.
Characters have little differences in height next to each other in different shots.
When Patrick is looking out Squidward's window, a black L shape appears next to the right side of Patrick's head for a split second.
