[Karl gives Hans a puzzled look]
Hans Gruber: Schiesse auf das Fenster!
[another puzzled look from Karl]
Hans Gruber: [clearly exasperated] SHOOT the GLASS!
Bob is trying to pass a clue or message on to Alice, but in a way that won't be too conspicuous. Perhaps he's talking in Igpay Atinlay, maybe he's leaning his head or eyes in the direction he wants Alice to look, he could even be winking. This may be a Quiet Cry for Help. Whatever it is, Alice is completely oblivious to this, or she thinks Bob is trying to say something else.
Sometimes, Bob will get so fed up with Alice's cluelessness that he'll finally decide "To hell with it," and shout the message, such as "TURN AROUND AND LOOK BEHIND YOU!" Other things may occur as well.
This can also be a character trait where a person is oblivious to any amount of Hint Dropping. The more annoying ones will misunderstand every attempt or interpret it as the opposite. In a particularly bad case you can't get it through them even if you spell it out for them or shout it in their face, and don't even bother with subtlety anymore. They might also be immune to criticism via Insult Backfire.
Related to I Do Not Speak Non Verbal (and occasionally, Non-Verbal Miscommunication). Contrast Selective Obliviousness, where the message is deliberately ignored rather than accidentally missed or misunderstood.
Characters who tend to suffer from this:
- Clingy Jealous Girl — when you tell them that She Is Not My Girlfriend
- The Thing That Would Not Leave — when you tell it to Get Out!
- The Cat Came Back — when you tell it that it's giving you Unwanted Assistance
- Resasuke from Aggressive Retsuko is completely incapable of understanding indirect communication. When Retsuko points out they've been walking a lot and asks if he wants to eat, instead of realizing she's tired and wants to take a break, he just says he's not tired and keeps walking with her. It's eventually made clear that this is one reason why he and Retsuko are ultimately incompatible with one another; Resasuke is never able to pick up on any hints Retsuko gives him that she's being worn down by their outings, and Retsuko is unwilling to confront him about it directly.
- Neon Genesis Evangelion: Shinji Ikari and Asuka Langley Sohryu like each other but both were too socially inept and frightened of other people to display their own feelings straightforwardly and realize each other's. Thus, Shinji always misses the constant hints dropped by Asuka (to be fair, he is clueless and oblivious but her hints might have been clearer), involuntarily making her feeling more worthless and getting her angrier.
- George Carlin complained about this in his last show, It's Bad For Ya. He discusses at people's inability to take a hint that they're boring the crap out of him, when he finally rants.
George: And while all of this is going on, you're searching through your mind for something gracious and diplomatic you can say to bring the conversation to a close; and all I can ever come up with is, "SHUT THE FUCK UP! SHUT THE FUCK UP! SHUT THE FUCK UP! SHUT THE FUCK UP!"
- Supergirl: In Supergirl (Rebirth): Plain Sight, Ben's blatant desire to take her to the next school dance in a not-so-subtle way goes unnoticed by Kara Danvers.
Kara: But this is meant to be an elite school— aren't we here to learn? This "dance" just sounds like a distraction.
Ben: Maybe sometimes people need a distraction. I take it you're... not interested, though.
Kara: Not in distractions, no.
- In Zits, Sara tells Jeremy that she's not supposed to have any friends over while babysitting, but she makes a point to state the address and time and how long the parents will be away. Jeremy takes it as a no-go, so Sara reminds herself that she has to be more straightforward with boys.
- Advice and Trust: After kissing for first time, Asuka asks Shinji why he had never responded any of her advances favorably if he liked her. Dismayed, she learns that Shinji was completely oblivious to her hints. In chapter 2:
She'd finally gotten that dense, oblivious, blind baka to finally notice the fact she'd been trying to get him to react to her hints that she... kind of thought he was cute.
- A Crown of Stars: At the beginning of the story Shinji finally finds out that Asuka had been constantly dropping hints, and he missed every one. Several characters also inform Asuka that Shinji had not responded any of her hints because he was oblivous and not because he was uninterested.
- Doing It Right This Time: After Instrumentality Asuka realized Shinji did not react to her hints because he was oblivious and clueless, not because he was not interested.
- The appropriately titled Teen Titans fic Dropping Hints starts with Starfire screaming in desperation because Robin won't ask her out. Raven recommends she stop being subtle, and start dropping a lot of hints for him. Then Starfire asks Beast Boy what that means... his answer is somewhat unusual, but at least it works perfectly.
- In Fantasy of Utter Ridiculousness, Patchouli is completely unaware that Jamie isn't talking with her solely to pass the time. All of Koakuma's attempts to spell it out for her fail miserably.
- Ghosts of Evangelion: After Third Impact Shinji tells Asuka that he wanted the same thing she did but he never got her hints:
Shinji: I didn't get what you wanted. I wanted the same thing you did, and I didn't get it. I just... I guess I just lost it in a different way.
- Last Child of Krypton: Despite having enhanced senses, Shinji is horrible at noticing hints. In chapter 2 Asuka meets him for first time. She stiffens and stares at him for several seconds before quickly looking away lest he notices she was staring. Shinji, despite of being able to sense the heat rising from her skin, misses this.
The second thing that happened was that Asuka Langley Soryu laid eyes on Shinji Ikari for the first time, and stiffened oh so subtly, her air of casual indifference shifting to one of deliberately indifference, her eyes rapidly snapping off him to look anywhere else before he noticed her looking. Shinji, being Shinji, despite being able to see the heat rising from her skin, hear the quickening of her heartbeat, and practically feel the sounds of the afternoon breeze brushing through her hair, of course noticed none of this.
- In Neon Genesis Evangelion: Genocide, Asuka's mental instability is partially owing to Shinji being incapable of noticing that she is constantly hinting that she likes him. After she wakes up from a coma, Shinji slowly gets better at noticing when she was dropping a hint.
- The One I Love Is: Shinji never got all hints Asuka had constantly dropped at his direction. Not even when she said she wanted to kiss him in chapter 4 he thought she might like him. She had to resort to blurt her feelings out blatantly.
- Subverted in The Second Try. Hikari thinks that Shinji is oblivious to all hints dropped by Asuka, but hes only pretending to not see them because no one can know that he and Asuka got together.
- In X-Men: The Early Years, Scott Summers is amazingly dense. Jean Grey drops all kinds of hints and he's still blind to the fact that she likes him back.
- In The Emperor's New Groove, Kronk can't figure out that Yzma wants him to knock Kuzco out until she finally slams her fist into her other palm.
- Beauty and the Beast (2017): Belle tries to tell Gaston that she'll never be interested in him without coming right out and saying it, but Gaston just doesn't get it. Of course, even when she does come right out and say it, Gaston still doesn't get it.
- Probably the funniest scene in the entire Indiana Jones series occurs in Indiana Jones and the Last Crusade.
Obvious Nazi agent: Welcome to Iskenderun. The Director of the Museum of Antiquities has sent a car for you.
Marcus: Oh, what? Your servant, sir.
Sallah: As I am his.
Obvious Nazi agent: Follow me, please.
Marcus: My reputation precedes me!
Sallah: There is no museum in Iskenderun.
Other obvious Nazi agent: Papers, please.
Sallah: Papers? [laughs] Of course! Run.
Sallah: Papers, sir, got it here. [pulls out a newspaper] Just finished reading it myself! [laughs] Run!
Sallah: Egyptian Mail, morning edition! Run!
Marcus: Did you say...? Uh, uh...
Sallah: [punches the Nazi agent through the newspaper] RUN!
- Men in Black:
- In the first movie, Laurel is trying to indicate to J that the Bug is in the morgue (and holding her leg under the table between them) by pointing down and repeatedly saying "I'd like to leave with you now" and "I have to show you something." J thinks she's talking about... something else....
- This exchange between the Big Bad and her sidekick in Men in Black II, when the former hears a suspicious noise in the kitchen:

Scrad: Oh, right!
- ¡Three Amigos! has Lucky making all manner of noisy bird-like calls to get the attention of Dusty and Ned. When they're sitting only a few feet away. He finally gives up and shouts at them.
- In Dragon Bones, Oreg tries to give the others (especially Ward, it may be assumed) hints that Axiel is a half-dwarf. He is really obvious about it from the reader's point of view, one time asking Axiel what a word he used means, and immediately afterwards calls Axiel a "grumpy old dwarf". Ward notices that Oreg seems a bit smug, and that the other person involved seems a bit irritated, but he doesn't understand the implications.
- In Fire and Hemlock, Tom desperately tries to make Polly understand that he is in danger of being made a human sacrifice, and she can save him by clinging to him (as friend) for nine years. He sends her fairytale books and everything, but she fails to notice it. Justified in that she's a child for most of the narrative, and the hints are very subtle.
- When Mrs. Bennet in Pride and Prejudice wants to leave Jane and Bingley alone together, she starts winking conspicuously at Elizabeth and Kitty so they'll leave. Elizabeth ignores her, knowing she's being tactless and stupid. Kitty, after a few minutes, asks why Mrs. Bennet keeps winking at her.
- In an episode of Deal or No Deal, Howie Mandel tried to show a contestant and her family that her sister had flown in from Boston to play one of the show's models. 
- Doctor Who: Pick a Doctor, any Doctor: you can't get more stubbornly blind than the guy who has to be outright trying to ignore something obvious (and sensible, or social). Much to the frustration of many a Companion.
- In one episode of Fawlty Towers, Polly keeps hinting to an oblivious Basil that their gourmet chef is deeply drunk, while Basil entertains dinner guests.
- Commonly with Gibby of iCarly, one example from "iWin A Date" when Carly and Sam set up a dating game on the web show so Gibby can be paired on a date with a girl he likes, but don't wanna straight up give him the answer.
Sam: Listen, there's three girls out there. Girl Number one, GIRL NUMBER TWO, and Girl Number three.
Gibby: But how will I know which one is Shannon?
Carly: If you want TWO choose Shannon, you have TWO choose carefully.
Sam: That's all you have TWO do.

- Jin in Dead Island just would not take no for an answer on helping the gangs who had taken over the police station. Despite the survivors and the gangs themselves telling her not to.
- Sierra Petrovita from Fallout 3. She is pretty naïve and is blind to the fact that her neighbor, Ronald Laren, is constantly hinting that he wants to have sex with her, and the Player Character can even tell her outright that Ronald "only wants to get in her pants", to which she responds: "Who would wanna wear an old pair of women's pants?"
- Alex of Captain SNES: The Game Masta discovers, to his dismay, that everyone around him is varying degrees of Oblivious to Hints when he tries to get them to leave so he can deal with the Sinastrals without posing a risk to anyone else. Molly is the most oblivious, to the point of standing there confused when Alex passes her a note telling her to run. And Boogerman ultimately figures out the message, but instead of doing what Alex wants, he simply announces, loudly, to everyone present (including the Sinistrals) what the message is and patting himself on the back for figuring it out.
- Mountain Time features a guy trying to get his friends to guess which hand he's holding a key in. Somehow, they don't even realize there's a key in question.
- EXO Next Door: Yeon-Hee doesn't realize until episode 13 that Chanyeol has been dropping her hints since they met, much less what they actually mean.
- Noob has a case in which the message isn't cryptic nor meant for the character, but the character is still lousy at picking up hints. Season 1 finale had the Noob guild discover that their dismal healer (Sparadrap) has a younger brother who actually knows how to play when he briefly takes over the avatar while the usual player is in the bathroom. In an early Season 2 episode, one of the guild's (other) members doesn't pick up on an elite player being Sparadrap's younger brother despite being present for a conversation that basically goes like this :
Elite Player: You're speaking to the leader of [game's best guild] Kevin.
Sparadrap: Hey, how do you know my real name? Do you play a the mindreader class?
Elite Player: Don't you recognize my voice?
Sparadrap: Err, no! But you do sound like my little brother! But that couldn't be! He's not here! I'm using computer! And he doesn't even know how to play! I try to teach him, but he runs off to the super café.
Elite Player: Cyber café. Just forget about it.
- In Kim Possible, Motor Ed simply will not quit hitting on Shego, no matter how emphatically she tells him (verbally and otherwise) that she isn't interested. If anything, getting plasma-blasted into the wall seems to make him even more attracted to her.
- There are many of these in The Simpsons:
- One of the best known is in "Bart Carny", when Homer and Bart are working the ringtoss booth at the carnival. Wiggum tries to get Homer to bribe him, (Bart, of course, gets it immediately) but after three tries (one of which includes mentioning his friend "Mr. Bribe"), Wiggum decides "screw this", and shuts the booth down. Later in the episode, Wiggum refuses to help the Simpson family when the owners of that booth took over their house. Homer still doesn't get it.
- In the episode "Cape Feare", the Simpson family is to be put in the Witness Protection Program so as to avoid Bart getting killed by Sideshow Bob. Two FBI agents discuss the family's new identity, and Homer is completely oblivious to the name change. Some time later, they are still unable to convince him to acknowledge his new identity.
