Prince Charles has delighted Doctor Who fans by impersonating a Dalek during a visit to the BBC's studios in Cardiff, Wales, yesterday.
Charles had onlookers — and himself — in stitches of laughter as he used a voice modulating microphone to utter the villains' famous "exterminate" catchphrase.
"Prince Charles’s attempt at being a Dalek was great," the show's writer Stephen Moffat said.
"I haven't thought about how I could weave a meeting between the Doctor and the royal family. But there would be a part in the show for him if he wanted it."
Charles, 63, has been a fan of the popular sci-fi series since he was 15 and was visibly delighted during his visit to the set.

He met the current Doctor Matt Smith and his co-star Jenna-Louise Coleman and posed with model Daleks.
He also got to play with a sonic screwdriver and step inside the famous Tardis.
"The Prince was lovely and a charming bloke," Smith said. "He took quite an interest in the Tardis' controls and asked a lot of questions about it.
"He told me and Jenna that he'd been a big fan of the show since he was 15 — which we didn't know.
"The other thing which stood out for me is he had fantastic shoes. He's got the makings of a future Doctor!"
