Worrying for the Wrong Reason

"Butch: Alright. I'll jump first.

Sundance: No.

Butch: Then you jump first.

Sundance: No, I said.

Butch: What's the matter with you?!

Sundance: I can't swim!

(Butch starts laughing hysterically.)

Butch: Are you crazy?! The fall will probably kill you!"

- Butch Cassidy and the Sundance Kid

One character expresses some concern about a situation. Another character corrects them, telling them what they should really be worried about. Not to be confused with Skewed Priorities, which is about being disproportionately concerned over something comparatively trivial, or with It's All About Me, which is about putting one's own interests ahead of everyone else's. This trope is about a character who has a legitimate fear that is then replaced with another legitimate fear.

A subtrope of Right for The Wrong Reasons.

"First fisherman: There aren't any sharks in here, are there?
 * This Castlemaine XXXX advert.

Second fisherman: Nah. Crocodiles ate all the sharks."

Computer Games
"Bernard: Have any people ever been hurt in this?
 * In the computer game Day of the Tentacle, Dr. Fred tries to send the main characters back in time using his... er... highly experimental time machine. Just before he turns it on, he and Bernard have the following exchange:

Dr. Fred: Of course not!

(Grins all around.)

Dr. Fred: This is the first time I've ever tried it on people!"

Film
"Because that pipe doesn't go to the marshmallow room; it goes to the fudge room!"
 * The most famous scene in Butch Cassidy and the Sundance Kid is built around an instance of this trope (and an aversion of Soft Water), as seen in the page quote.
 * The film Willy Wonka and the Chocolate Factory has Augustus Gloop get stuck in a pipe. His panicky mother shrieks that he'll be "melted into marshmallows," to which Wonka responds that the very idea is patently absurd.

Literature

 * When the Animorphs find themselves on a cliff on the meteor-wrecked Hork-Bajir planet, they notice the planet's molten core far below them. One character worries about the possibility of falling into the magma. Ax says that this won't happen -- if they fell, they'd be vaporized by the heat long before they reached it.
 * Making Money introduces the drink Splot, a sort of Klatchian Coffee Up to Eleven. People are often reassured when they hear Splot is nonalchoholic...until they're told it's because "alcohol wouldn't survive."
 * And in The Last Continent, there are very few poisonous snakes in XXXX... because most of them have been eaten by the spiders.

 * Firefly: When Serenity's engine breaks down, shutting down life-support, the crew worries that they'll suffocate. River informs them that they don't have to worry about that; they'll freeze to death long before the air runs out.
 * On an episode of Buffy the Vampire Slayer, Xander is in a panic because he has been cursed with a host of diseases. He's most stressed about the syphilis. Anya says comfortingly:


 * Played with in Red Dwarf when the captain of the ship is talking with the ship's A.I about the crimes they are imprisoning the main characters for (they are innocent of those crimes) and then adds that they committed other crimes that have an equal imprisonment time.

"Ennesby: Uh-oh. Those look like real police.

 * Peter Kay's standup act relates the story of a meal interrupted by a cellphone call from a child who's scared to go to sleep because of monsters in his cupboards. Our hero tells him he needn't worry about monsters in his cupboard - it's burglars breaking into the house he should be worried about.
