Slipping off the serious road here to highlight what is probably the most famous utterance of the title of this post...

THE LIFE OF BRIAN
SCENE 9: THE COMMANDOS

REG: They've bled us white, the b*****ds. They've taken everything we had, and not just from us, from our fathers, and from our fathers' fathers.
LORETTA: And from our fathers' fathers' fathers.
REG: Yeah.
LORETTA: And from our fathers' fathers' fathers' fathers.
REG: Yeah. All right, Stan. Don't labour the point. And what have they ever given us in return?!
XERXES: The aqueduct?
REG: What?
XERXES: The aqueduct.
REG: Oh. Yeah, yeah. They did give us that. Uh, that's true. Yeah.
COMMANDO #3: And the sanitation.
LORETTA: Oh, yeah, the sanitation, Reg. Remember what the city used to be like?
REG: Yeah. All right. I'll grant you the aqueduct and the sanitation are two things that the Romans have done.
MATTHIAS: And the roads.
REG: Well, yeah. Obviously the roads. I mean, the roads go without saying, don't they? But apart from the sanitation, the aqueduct, and the roads--
COMMANDO: Irrigation.
XERXES: Medicine.
COMMANDOS: Huh? Heh? Huh...
COMMANDO #2: Education.
COMMANDOS: Ohh...
REG: Yeah, yeah. All right. Fair enough.
COMMANDO #1: And the wine.
COMMANDOS: Oh, yes. Yeah...
FRANCIS: Yeah. Yeah, that's something we'd really miss, Reg, if the Romans left. Huh.
COMMANDO: Public baths.
LORETTA: And it's safe to walk in the streets at night now, Reg.
FRANCIS: Yeah, they certainly know how to keep order. Let's face it. They're the only ones who could in a place like this.
COMMANDOS: Hehh, heh. Heh heh heh heh heh heh heh.
REG: All right, but apart from the sanitation, the medicine, education, wine, public order, irrigation, roads, a fresh water system, and public health, what have the Romans ever done for us?
XERXES: Brought peace.
REG: Oh. Peace? Shut up!

This is just an exert from Life of Brian and if you haven't seen this film and are not easily offended I suggest you do... My own personal favourite would be Scene 12 with the introduction of Pontius Pilate. It makes me laugh every time no matter how many times I watch. No one is safe from criticism - not the Romans, nor the Jews, Christians or Samaritans

Enjoy!
