A long time ago, in another life, I went to a screening of "The Great Rock'n'Roll Swindle". As this was a midnight show in middle of town, most of the audience in the packed theatre would have been placed at the inebriated end of the sobriety spectrum.
Unsurprisingly, there was plenty of heckling through the film until, about 15 minutes in, the film stopped, the lights came up and about 30 police came in, a couple of them with dogs who were woofing loudly at the "atmosphere" in the theatre.
Sergeant Knobsworth stood at the front, beneath the screen and started to offer a bit of fortune-telling, predicting the next 30 minutes in the lives of the audience members who continued their disruptive behaviour, with the dogs woofing loudly.
One self-appointed joker towards the middle of the theatre shouted out "Give the dog a bone!"
The dog-handler, who had a deep, loud voice which he could project magnificently, instantly said "I'll give him one of yours if you don't sit down and shut up!"
Much laughter, much piss-taking of the joker and that was that. The perfect line, the perfect delivery and everyone was sitting down to watch the rest of the film, which passed without incident.
