One of those scenes where the villain says; “I’m going to count to three and if you don’t tell me what I want to know I’ll kill you.”
The hero says, “I’ll tell you what you want to know, but could you count to three anyway just to show me that you can.”
As I recall, the next sentence was something about how, starting at 60 seconds, all the air was evacuated from the level the other scientist was on, so it actually was only about 15 seconds to spare.
You’re probably right; I haven’t read that book in, most likely, 30 years. You think that was some kind of ironic joke the other scientist was making? Have I been whooshed all these years? I hang my head. 
The Doctor Who version:
Evil Alien: “Kill the Doctor! Kill him NOW!”
The Doctor: “Ah, but wait! There’s someth-” ZZZZAAAAPP!

[ur=Evil Overlord List - TV Tropes]Ah, yes . . .
Cue Austin Powers reference…
Villain does threat in stereotypical evil raspy voice.
Hero asks if it hurts his throat when he talks that way.
“I shall give you to the count of three, Mister Bond or the girl dies. One…”
BANG!
“I never was that good at math.”
Bruce Willis and Tracy Morgan did just that to the villain at the climactic scene in Cop Out.
I was hoping someone would get it! 
One I think I’ve mentioned here before goes roughly like this: Grand Moff Tarkin speculates that Princess Leia may be of some use to them after all, and orders Vader to bring her to him.
Vader replies, “That girl you told me to have terminated immediately like 3 hours ago? Dude, that boat has sailed.”
The bomb threat is announced. Nobody screams. Everyone stands and calmly forms a line to exit the room. As time runs down, they begin to trot – in unison.
Planning a bank robbery:
Once the silent alarm goes off we will have 90 seconds to grab all the cash we can and get out.
-90 seconds, how do you know that? In order to know that you would have to know the location of every cop car in the city on the day of the robbery. How can you possibly know that?
Its just a guess really, I’m really just saying we should go as fast as possible. Obviously, the faster the better, but I thought it would sound more authoritative to put an actual number to it.
That would make an awesome scene in a Naked Gun-style comedy 
A plucky young female athletes fights/sues her way onto a men’s football team… then immediately takes a big hit, breaks several bones, and is carted off the field.
Along these lines, the plucky young female heroine fights the big burly brute… and gets beaten badly, requiring the (larger) male hero to intervene to save her.
Hey, there’s a reason why fighters are grouped into weight classes.
Grand Moff Tarkin: You may fire when ready. And this time, remember to close the blast doors over the exhaust ports on the heat exchanger; we don’t want another blowback like we did when we blew up Alderaan.
Villain, to hero who’s just grabbed a gun: “What do you think you’re doing with that? You don’t have the courage to pull the-”
Hero: BANG!
(props to Kiss, Kiss, Bang, Bang for actually going this route)
I saw this in an anime. This particular villain was virtually unkillable, even beheading him wouldn’t take him out unless you kept the pieces apart. So one of the heroes sets a trap, blows him into small pieces that are spaced out in a large pit. Then he fills in the pit with rocks and dirt. Then he sets a guard on the covered pit.
