This passage is from The Ferryman (jez Butterworth) What "Herberts" means?
MAGENNIS. When I was a kid we used to go out to my grandfather’s place down in Fermanagh there, and help with the harvest. It was good craic. Got us out the smoke. Out in the fresh air. Harvest time’s a fine time of the year, so it is. Pause. Well, I’ll get straight to it. (Beat.) Three days ago, there’s two turf-cutters cutting turf in County Louth, just across the border there, when they come across a body in the bog. (Beat.) Now they’ve read the stories in the press about prehistoric finds, your Stoneyisland Man, your Tollund Man there, two thousand years old, and how the people that find them become famous. They’re hatching all these dreams, TV interviews, prize from the National Museum and whatnot, when one of ’em spots that your man’s wearing a pair of Gola trainers. A Timex wristwatch. Brown corduroys. (Beat.) So they rummage through his pockets and they find his car keys. His last pay packet from December 1971. Some Polos. A betting slip signed on the back by Georgie Best. A picture of his wee’un. (Beat.) So your two Herberts there call the Garda, and they run a quick check of your man’s dental records, and they come up with a name.
