"I'm surprised you can work this well when you're so drunk."

He was clearly a bounder and a cad. He seemed to think because he was the possessor of the finest legal mind ever discovered that gave him the right to behave exactly as he liked, and unfortunately he appeared to be right.

"I may not look like it, but I am a professional!"

"You will be dealing with a highly strung and temperamental team of rank amateurs who just happen to be brilliant at what they do."

Harry: Bunny slippers and polka music.
Murphy: Don't knock it. He's good at his job.

"I just wanted you to know that besides the murders, and you trying to kill me, you were the best doctor I ever had."

Watson: I don’t think you need alarm yourself, I have usually found that there was method in his madness.
Inspector Forrester: Some folk might say there was madness in his method.

"It seems you can't hire someone competent without them having an embarrassing hobby."

"People think I'm kidding when I tell them that the same guy who used a homemade grappling hook when the elevators were out is also the reason why this company is showing record profits."

Sarah-Jane Smith: Are you serious?

The Doctor: About what I do, yes. Not necessarily the way I do it.

The guy singing is a lawyer. This motherfucker is a lawyer. THIS. Motherfucker. Is a lawyer.

"Despite his eccentricities and cynical... och, he'll appreciate the honesty... downright unpleasant personality, Mr Montag does more for the safety and development of his students than he lets on. It's not an easy thing bringing these kids into a world frought with occult rites and secret handshakes: it takes a real bastard, even on the best of days. The competition for the most talented students, the petty jealousies and the ancient blood feuds between the most prominent institutions, and the more-and-less covert attempts at industrial espionage all take their toll... and of course, the deaths. Being responsible for every single life lost in the pursuit of knowledge would break less than an arrogant man. At least he lets us deal with the parents now: after those first couple of accidental self-immolations, some thought it best we kept him away from grieving relatives."

For top-level work, you need Zero pilots. Such men are not bound by the same rules as the expendables. If one of them feels like having a few drinks to relax after a hard day's work serving Allah, so be it.
To a war commander, the higher the skill level, the higher the tolerance for off-duty conduct. Your best sniper has a preference for little girls, your top chopper-pilot's hobby is rape - so what?

"The son of a bitch is the best doctor we've got"

"You have a rather insubordinate subordinate, General."

"Just remember, I retired! You wanted me back!"

"Got your hands full with that one, eh, George?"

Mr. Wiederspann: Uh, Arthur, I'm afraid the firm feels that... It's time to allow you the opportunity to... Pursue other avenues of employment.
Arthur: I'm fired? Is there a problem with my work?
Mr. Wiederspann: Oh no, Arthur, no. It's, it's, it's... It's that stupid bunny outfit!
Arthur: Oh no, not "bunny" sir: Moth. It's my moth suit. Actually, it's a flying suit. The wings are in my briefcase.
Mr. Wiederspann: Arthur, you're making the other accountants nervous. We all find this kind of... Rampant individuality... Very disturbing.

"People will tolerate how unpleasant you are if your work is good and you deliver it on time."
