Britain's Prince William and Harry were given the nickname "sausage" by an electrician on the 'DIY SOS' team.
The royal brothers, who helped the television team of experts turn a derelict street into homes for ex-service personnel, were stunned when sparky Billy Byrne referred to them in his usual way while working on a refurbishment.
Presenter Nick Knowles told the Radio Times magazine: "Having met them before, I was aware they don't particularly want to be walking round a building site and being called 'Your Royal Highness.' They told me 'You can call us William and Harry.' So everybody was quite happy to call them that."
He added: "Apart from our electrician Billy, who called them 'sausage'. But then he calls everybody sausage.
"Harry said to him: 'If you're going to call me sausage, it's going to be a very long day."
William, 33, and Harry, 31, slipped on personalised hard hats and steel-cap boots as they got stuck in a helped renovate two whole streets in Newton Heath, Manchester.
The project, which took three weeks to complete, saw eight buildings undergo work for the injured servicemen and women, while another 62 houses were rejuvenated.
The episode of 'DIY SOS' featuring Prince William and Harry will air on BBC on October 14 and 21.
