There is excitement in the canteen when news of a royal visit to the factory comes through. Nobody's very sure who's coming - Princess Anne doesn't do factories, Prince Edward does theatres - but they're all getting into a flap. When it turns out it's someone called the Duke of Danby, nobody has heard of him, save for Stan, who met him at Catterick years ago. Everyone throws themselves into role play and preparations: Twinkle has to be warned not to say they serve "arseholes on toast" and Anita is worried about her nipples popping up. Tony is adamant that the royals aren't speaking to the girls - God help the Duke if he does. When they eventually turn up, Twinkle's struck dumb, Anita says the wrong thing and Stan's devastated that the Duke doesn't remember him. Meanwhile, all the Duke wants is a bit of sex with poor Bren.
