Whamise this line. A Game.

Someone posts a line of dialogue and someone else imagines a set of circumstances following which the line in question, if said y a character, could be considered a Wham Line. And so on.

"What kind of man do you think I am?"

Sure, why not.

The line is spoken by the "Hero Antagonist" the Villain Protagonist has been fighting throughout the entire work thus far. This is where our protagonist finds out he's actually been fighting an Anti-Hero or even a Villain with Good Publicity all along... and as a result, the protagonist's Batman Gambit relying on his opponent's good alignment is collapsing around him. Now, for the next fellow:

"You've forgotten about the cows."

Farmer Greene just thanked you for saving his life from a burning barn, but you forgot about the demonically possessed scythe-wielding bovine now gathering behind you.

"I remember this...this is exactly what happened nine years ago."

In a competition for something, there is an unbeatable team that the heroes have to defeat. But the other team's strategy is completely solid. Until the veteran member speaks the lines, and realizes that he himself had created the initial structure of that very strategy 9 years ago.

"It's not magic. It's technology."

Sauron: "Pay no attention to that man behind the curtain."

Frodo: "So the One Ring was just a device to deliver nanotech to Hobbiton."

Clockwork Hobbit: "Kill them all!"

Next: "I had it a minute ago...."

Aliens are invading Las Vegus, flying above the skyscrapers. The alien leader just send a message that in thirty minutes, unless what was in Area 51 is returned, they would raze the city to the ground. Who will save them...?

"Hey. Is that a policebox?"

In the metafictional multiverse, objects from one universe appearing in another is a sign of the fabric of the multiverse giving way, and the TARDIS is not supposed to exist in Star Wars.

"Stop pretending you know what you're talking about."

A commanding officer of the local militia has had it up to here with a local kid's pompous sense of "I'm right on this". Instead giving him the harsh reality that war is not some kind of game.

"You know what they say, if you leave your windows open at night the fairies come and rip your guts out."

The protagonist looks down at the mutilated body of his friend in a poorly lit morgue. One of the detectives who'd called him there to identify the body comes up behind him, and whispers something in his ear that made him jump, in spite of the silliness of the detective's advice. He could recall another person giving out cryptic advice about "fairies." The man had been addressing his friend the day before his disappearance, and it had been pretty clear that the "fairies" he'd been talking about were more the "codenamed mob hitmen" type than the cute little winged creatures from Disney. The detectives advice had two purposes: one, the inform the protagonist that he had the police in his pocket, and two, that the protagonist would be next if he didn't keep his mouth shut.

"Why do I get the feeling I shouldn't open the toilet seat?" (if you can make Toilet Humor dramatic, you win.)

A bunch of teenagers are at a party, and one of their friends went missing an hour ago. By now, they're starting to get seriously worried, and so they head into the girls' toilets, the place she was last seen heading towards. When they enter, they notice that the room is empty, and the lights have shattered in their sockets, but one of the cubicles is locked shut. Looking under the door, they can see no-one occupying it either. Eventually, they force the door open, only to find... absolutely nothing. The cubicle is completely bare.

They're about to leave when one of them swings his torch over the toilet, and notices a faint red smear on the lip of the bowl...

My turn. "Biscuits, anyone?"

A crew of a sailing ship is lost at sea searching for land. Their food supplies are low as is their morale. The revelation that biscuits is all they have left hits home just how badly they have it.

"No John, you are the murderer."

The trauma of committing the crime caused John to have amnesia. Jane finally decided the only way to get him to snap out of it was by being as straightforward as possible.

"So, the fact that this idea is completely untested doesn't faze you?"

The Captain of the Starship Los Angeles has lost his marbles during the war against the Zodons of Quadrant 45A, and decides to turn the ship into a quantum bomb to destroy every point in time and space that the Zodon's habitate. The AI tells him that this method has never been tested before, but the Captain's too far gone to realize the implications of tearing a hole in the universe for extermination, and lets everybody know it.

Next one: "Aw, crap. It's the 12th, isn't it?"

Miyaka has had fun all throughout the year doing all manner of adventures. But being reminded that tomorrow's the 12th makes her remember that finals occur that day and that she hasn't prepared at all.

"It came down from the mountain in search of something or someone."

The merciless beast tearing people apart for the past month has actually been looking for the treasures stolen from its cave several years ago, and not just mindlessly killing people.

"Where'd the door go?"

A group of characters discover a portal to an alternate universe in their closet. Now they can't get back to theirs.

"Don't eat yellow snow."

This seemingly puerile piece of advice is relevant to our band of adventurers. It is because yellow snow is indicative of poisonous sulfur deposits on the snowy flanks of the mountain owing to its active geological system. In order to avoid a grisly death all efforts must be made to retrieve water from the snow only where it is known to be safe as they travel.

"Last week there were dancing lights over the mountains, three days ago a forest mysteriously turned flat, yesterday all radio stations became replaced with a weird droning noise. No Mr. Cooper this is not a natural phenomenon, this is an invasion."

Mr Cooper is a worried farmer and the speaker is the mayor of the city whose face begins to peel off as he speaks - revealing an alien beneath.

"There's no way that can be a unicorn."

Bill is explaining to his younger sibling that, despite the markings on the animal that he'd seen, the younger sibling was wrong about its species.

"Well, paint me blue and try to kill me!"

Bob has just come to the horrifying realization that they are currently living the plot to Avatar.

“Don’t worry I’ll be home Wednesday”.

Jake is too far away to be home by Wednesday, so the teleporter must be working.

"What are you talking about? I'm lactose intolerant."

Nice Job Breaking It, Hero, your brilliant plan to save your love interest by feeding her milk while she was unconscious actually just lead to her inevitable death!

"The hills are upside down! The hills are upside down! The hills are upside down! ..."

The protagonists realize they're not doing a headstand on the hills. They're walking perfectly normally on the sky-patterned mountains.

"I can't find my car keys."

The farmer was about to start his truck when he sees a spaceship land inside his barn. Hesitantly exploring, it turns out the spaceship has a shapeshifting organism which immediately devours the farmer first chance it gets. After mutating into the farmer and running through his memories — after dressing itself up and checking its looks, it asks his wife where the car keys are at.

"I need you."

The protagonist is being chased by a horde of zombies, and after an exhausting chase, she finally makes it to her car...only to find out she left her keys at home.

The protagonist is reaching the end of the line. Here he is, in the middle of the Arctic tundra. His entire crew has gone missing, along with all their food, supplies, and scientific equipment, and he'd rather not think about how. But he knows. They're coming to get him. He had only wanted to advance the cause of science. But here he was, buried in the sand to hide from them. It was very cold. He thought of his mother, who had raised him on her own, who had always stuck by him, who had loved him completely and unconditionally. He wanted a hug. He needed her.

"Many have resisted before. Perhaps you're just weak-willed."

Edit: Ninja'd.
