When he was “negotiating” with Hans Gruber, he was so abrasive and asinine, I couldn’t believe he managed to negotiate any deals at all. I was thinking to myself, this is the worst negotiator ever.
Once again, John McClain wasted a golden opportunity to pop him, just standing there talking to him. Moral of the story: when bad guys are standing in front of you, and you have the gun and they don’t, shoot them. Quickly. Before it’s too late.
He certainly was typical of the dealmakers in '80s movies, though. A lot of the old-school shmoozers act like that IRL. They’re much cooler in their own heads than they are to the rest of us.
And then the movie is very short. 
Didn’t we just give a bunch of these cocks 700 billion dollars?
And you thought they couldn’t negotiate any deals…
That hand-held radio John McClane has is by far the best radio ever in the world. Another example of fine German engineering.
Amazing battery life, too, especially before ubiquitous lithium ion cells…
Incredible battery life, absolutely crystal clear reception a mile away in the middle of concrete and steel high rise structure. No noise of any kind, whatsoever.
And again, if the angry Russian bear here had just shot McClane when he had the chance, the bad guys would win and be sitting on that beach…
Hans Gruber: I’ll blow the roof full of all the hostages, and kill them all.
FBI: We will neuralize all the terrorists, with the hostage losses at 20~25%. Tops. … (smiles) Yeah, I can live with that.
The difference between terrorists and the FBI: 75%
That’s so unfair. It’s at least 75-80%. 
“Holy! Christ! We’re gonna need some more FBI guys, I guess.” 
Giant fireball of an explosion.
Moral of the story: do not use the rooftop to store barrels and barrels kerosene. Also, do not use tactical helicoptor to ferry barrels and barrels of kerosene.
Did he just say “Allez, allez, vite, vite?” I thought they were German.
(He was from everywhere.)
Ich habe un problemo avec diese gravity. 
Jesus, what kind of god damn hand canon is that black cop carrying? (Is it canon or cannon? I forget. One’s artillery and the other is a digital camera. I get those mixed up.)
(BTW, another example of an occasion where, if McClane had just bothered to put a bullet in him, instead of just assuming that he was dead, they could have avoided a lot of trouble.
“It’s an .88 Magnum. It shoots through schools.”
Do you know the reference, without Googling?
Nah, gotta look that one up.
ED: Holy crap, it’s Michael Keaton!
Actually, it was Joe Piscopo, although he only said the second part. Don’t know off the top of my head who said the first.
The great cinematic masterpiece that gave the world “you fargin’ iceholes!”
Yup, I liked that movie. Johnny Dangerously.
BTW, this is a consistent problem I’ve noticed in myself since 2000 or so. I’ve become so good at Googling (or, before Google, digging through Yahoo directories, or ferreting things in Usenet, etc.) that my memory has been in a constant decline for a while. I have become very bad at retaining any information, because there’s no need to. I can Google things faster than I can actually remember them. I can actually physically tell that the logic and reason portion of my brain is evolving forward, and the memory retention portion of my brain is eveolving backward. Rapidly.
