"Mr. Madison, what you've just said... Is one of the most insanely idiotic things I have ever heard. At no point, in your rambling, incoherent response, were you even close to anything that could be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul."
Principal Max Anderson, Billy Madison

Sometimes when a plan or idea is proposed the regular insults and even a Face Palm just don't cut it. Nope, they've crossed the line into what can be called a Crowning Moment of Stupidity, and the witness feels the need to comment on this.

Variations can include "dumbest" "most idiotic" "most ridiculous" etc., but the same basic message applies.

May be combined with Who Would Be Stupid Enough...?. Contrast Crazy Enough to Work. If the person being castigated winds up being correct, this can become The Cloud Cuckoolander Was Right.

Examples of Stupidest Thing I've Ever Heard include:

Anime & Manga

  • In the dub of Mobile Suit Zeta Gundam, Haman says this when Kamille suggests that killing Earthnoids isn't justified.

Comic Books

  • X-Men
    • Danielle Moonstar uses this against Cyclops early in New X-Men: Academy X, when the latter suggests keeping from their students that the corpse of their recently deceased teacher has been stolen, and that he might return as a brainwashed zombie.
    • Not the Exact Words, but in Astonishing X-Men, Kitty Pryde attempts to inspire one of the students with a heartfelt speech about how mutantkind would never want a cure for their mutation. The kid's response, understandably, is "Ms. Pryde, are you fucking retarded?"

Fan Works

 Harry: [Dobby's] apparently gotten it into his head that Hogwarts is a walking death trap and therefore I'm better off with my Muggle relatives and in particular my Muggle uncle who could snap at any time and try and strangle me. Therefore, he sealed the portal to the platform and Ron and I got bored so we decided not to wait for everyone to fix the mess and just fly here.

Draco: That has got to be the stupidest thing I've ever heard.

And later there's this...

 George: Besides, the Slytherin team apparently couldn't find anybody to spy as they showed up in person. And full Quidditch gear.

Harry: Why in the world are they wearing their Quidditch robes to practice in? That has got to be the stupidest thing I've seen all day.

Fred: All day isn't very long, Harry. It can't be more than ten.

 Yugi: THAT is the stupidest thing that has ever come out of your mouth. Card games on motorbikes. Come on!

 Marge Simpson: Homer, in every marriage you get one chance to say, "I need you to do this with me."

  • In Jimmy Neutron Boy Genius, this exchange occurs after Sheen relates the current situation to an episode of Ultra Lord:

 Nick: Well, folks, that is just about the stupidest thing I've ever heard!

Sheen: No, this is the stupidest thing you've ever heard! (starts jabbering)

 Pumbaa:Maybe he'll be on our side?

Timon: That's the stupidest thing I ever heard, "maybe he'll be on..." Hey, I got it! What if he's on our side?

Films -- Live-Action

  • In X-Men, after Professor X tells Wolverine several code names such as Storm, Cyclops, Magneto, and Sabretooth. Hypocritical Humor on his part, since he has a code name of his own.

 Wolverine: What do they call you? "Wheels"? This is the stupidest thing I've ever heard.

 "Well, I've been to one world fair, a picnic, and a rodeo, and that's the stupidest thing I ever heard come over a set of earphones. You sure you got today's codes?"

 Judy: Love means never having to say you're sorry.

  • In Heathers:

 Veronica Sawyer: I'd like to ask you a stupid question.

Jason Dean: There are no stupid questions.

J.D.: That's the stupidest question I've ever heard.

  • In Star Trek IV: The Voyage Home, Chekov has traveled back in time to the 20th century and been captured by the Feds. But they don't quite know what to make of him:

Agent #2: He's a Russkie.

Agent #1: That's the stupidest thing I've ever heard in my life. Of course he's a Russkie, but he's a retard or something.


 Sirius: Our information from inside the Ministry is that Fudge doesn't want you trained in combat.

Harry: Trained in combat? What does he think we're doing here, forming some sort of wizard army?

Sirius: That's exactly what he thinks you're doing. Or rather, that's exactly what he's afraid Dumbledore's doing -- forming his own private army with which he will be able to take on the Ministry of Magic.

Ron: That's the stupidest thing I've ever heard, including all the stuff that Luna Lovegood comes out with.

    • Of course, Harry decides to do exactly that, train his fellow students in a group he calls "Dumbledore's Army". Not that they are going to take on the Ministry of Magic, but Voldemort.
  • Sean Devine in Mystic River says this when his partner Whitey suggests a theory for the murder they're investigating, that Dave Boyle, Sean's childhood friend, killed Katie Marcus. In the end Sean was right, and while Dave did kill someone, it wasn't Katie.

  • From the Cheers episode "Little Sister, Don't Cha"

  • In The Cosby Show, when Cliff confronts Theo about his grades, Theo goes into a spiel about how being an educated professional was fine for his parents, but that wasn't the path he wanted in life and his family should accept him the way he is. The anticipated 'Awww' hug scene is averted when Cliff tells him "Son...that's the DUMBEST thing I ever heard in my entire LIFE! No WONDER you get D's in everything!"
  • The Colbert Report has an occasional feature called "The Craziest F#@king Thing I've Ever Heard," a parody of Bill O'Reilly's "Most Ridiculous Item of the Day."

Bartender: Your own way?

Steve: She accidentally overheard me saying it on the phone, when I thought I was talking to my ex-girlfriend.

Bartender: No offence, and, of course, it's none of my business, but that could be the worst proposal in human history.

Sally: Steve, you're gonna have to be my husband. Patrick prefers blondes!

Bartender: I love this bar!

  • Superhuman Samurai Syber-Squad: In one episode, Amp's idea to prepare himself for a test was literally eating the books. Malcolm stated it was the dumbest idea he ever heard and that's considering Malcolm heard Amp saying really dumb stuff before.

  • Subverted in Left 4 Dead 2. Coach comes up with an idea to start up a band's pyrotechnics in order to call for a helicopter. After hearing this, Nick drops this line.

  • In Sam and Max Hit The Road, after hooking it up so he can do so, Sam proudly declares that he can control the rotation of a rotating restaurant on top of the world's largest ball of twine via a pair of mounted binoculars. Max informs him that this is the most ridiculous thing he's ever heard. It may very well rate pretty high in that category. Even better, since Hit The Road was made during the dark ages long before Microsoft caught on to the concept of hardware abstraction the UNIX world had years earlier, it had its own audio hardware configuration tool. The sound clip used as a test to make sure your hardware was working correctly was Max saying that very line. So yes, this can even be considered a meta-example of sorts.
  • Most of Black Whirlwind's stories in Jade Empire allows your main character to respond with this line.
  • In Escape from Monkey Island, Guybrush talks with Ignatius Cheese, who tells him that keeping Ozzie Mandrill out of the Scumm Bar has taken all of his Insult Arm-Wrestling skills. Guybrush comments that "If it weren't for the whole, 'Wife being declared dead' thing, I'd say that was the strangest story I'd heard all week." This gets a Call Back later when Meathook tells him how he taught himself to paint using his hooks and coloured candle wax. Guybrush replies "That's the silliest story I've heard in hours."

Web Animation

 Roy: Well, I would say that's the dumbest thing I've heard all day, but as I've been talking to Elan since morning, it might not even crack the top ten.

  • Eight Bit Theater: Red Mage tends to trigger this in his "comrades", but the best example may be 1150. "That is quite literally the least practical plan put together by an allegedly thinking creature."

  • Freakazoid gets this opportunity after The Lobe tells him all about his plan to use a giant cloud to turn people into zombie clowns. Freakazoid scowls, and simply replies, "Well, if you don't mind me saying so, that is the stupidest plan I've ever heard of!" and rants about its ridiculousness until the Lobe is reduced to tears. This is almost immediately subverted when, after the Lobe leaves, Freakazoid immediately starts laughing and exclaiming that the plan is a brilliant one.

Not the people at the table. The table. To realize how absurd the comparison to Naziism is, recall that Barney Frank is both Jewish and gay.
