Quick Draw Decision

Villain: "I'm going to kill your daughter, Sophie. But only one of them. Now, which one should I-"
Sophie: "The ugly one."

—Family Guy

Someone is faced with a difficult choice, perhaps a Sadistic Choice. They will undoubtedly need to spend a few moments thinking it over, perhaps Wangsting a little, and-

Oh, they already decided. That was quick.

This trope is when a character responds far more quickly to a decision than the viewer or the other characters expect, usually played for comedy. Maybe it's a choice you'd think would be difficult, but the character knows what they want without even having to think about it. Or maybe, even if the choice isn't difficult, you still expect them to take a moment to phrase their response in a polite way, but they instead respond with incredible bluntness. Sometimes characters won't even let someone finish listing the options before automatically making their choice. This response can be shown as good or bad depending on the circumstances and the writer's whim.

Examples of Quick Draw Decision include:

Film

In GoldenEye, the villain has the Distressed Damsel at gunpoint and says he'll shoot her if Bond doesn't surrender. Bond's response: "Kill her; she means nothing to me." Subverted a few scenes later when he reveals he was just calling the other's bluff; then parodied later still when their positions are reversed and she says this of him.

Live-Action TV

In Firefly, Zoe picks her husband, Wash, before Niska can even offer the Sadistic Choice between him and Mal. "I'm sorry, you were going to ask me to choose, right?"
In an episode of Angel, Wesley's father shows up and turns out to be a bad guy. Even after this revelation, Wesley can't bring himself to shoot his dad. But the instant his father points a gun at Fred, Wes shoots him seven times before he can even finish the threat. It turns out that was just a robot designed to look like Wesley's dad, but Wes didn't know that.
- When Faith takes up a contract on Angel, she offers him a gun to make things interesting; Angel immediately shoots her in the leg. Unfortunately It Works Better with Bullets.
How I Met Your Mother did the rude variant when Robin found an engagement ring in her champagne and thought Ted was proposing to her. "No. No no no no no. Ted, you cannot do this to me. No! No no no!"
On Friends the gang is discussing whether they'd give up sex or food if they had to. Monica instantly shouts "Sex!" Her boyfriend Chandler can only say "Seriously, answer faster!"
- Phoebe uses the Quick Draw Decision to get at what you really want even if you don't know you want it. Joey doesn't know whether he wants to take the north or south route to Las Vegas.

Phoebe: Which do you like better peanut butter or egg whites?
Joey: Peanut butter!
Phoebe: Which would you rather be a fireman or a swimmer?
Joey: A swimmer!
Phoebe: Who would you rather sleep with Monica or Rachel?
Joey: Monica. Oh...huh, I always thought it would be Rachel.
Phoebe: No thinking! No thinking! Tie or ascot?
Joey: Ascot!
Phoebe: North route or south route?
Joey: North route!
Phoebe: Bam! There you go!

Joey then tries this with Ross, with disastrous results... mostly because he reused Phoebe's "who would you rather sleep with" question.

Web Comics

Web Original

One Yu-Gi-Oh!: The Abridged Series episode also uses the rude variant. Yugi asks Tea if she might ever possibly consider going out on a date with him. "Never in a million years. Why?"

Western Animation

The Simpsons:
- In The Simpsons Movie, President Arnold Schwarzenegger is given five folders, each one containing a potential response to the Springfield situation. He doesn't even open any of them before picking #3. "I was elected to lead, not to read."
- In an episode where it looks like Homer and Marge might get divorced, the kids are asked to think about which parent they might want to live with. Bart and Lisa both answer "Mom!" before the question has even finished being asked.
- And again, in a Halloween episode, Lisa is selected to come aboard a space ark meant to save the best and brightest. She is told she can only take one of her parents and answers "Mom" before the question is even finished.
  - Homer's response is typically... Homerish...

Homer: Goodbye, Lisa. I want you to remember me just as I am... filled with murderous rage!

In an episode of Duck Dodgers, Dodgers is given the powers of a Green Lantern. After the other Lanterns are captured, Sinestro offers him a chance to join him. Dodgers agrees so quickly that at first Sinestro doesn't even realize what he said. In fact, he's disappointed that he doesn't get to do the whole "villain seduction speech". Dodgers lets him do it anyway.
