That's a turnip for the books – Sir Tony Robinson, famed for his role as Baldrick in Blackadder, has landed a top children's literature prize.
The actor, also noted for his years fronting Channel 4's Time Team, has collected a Blue Peter Book Award in the factual category of the annual prize run by the CBBC show.
A panel of judges and young viewers had a say on the winner, with Sir Tony's Weird World Of Wonders: World War II book triumphing.
Newcomer Katherine Rundell, 26, was also a winner with her second novel Rooftoppers named best story.
Sir Tony's character Baldrick, who was noted for his love of turnips, once showed off his literary prowess by writing a semi-autobiographical story which read: "Once upon a time, there was a lovely little sausage called Baldrick and it lived happily ever after."
The actor and presenter – who has written more than 20 books – also won a Blue Peter prize in 2007 for his Worst Children's Jobs In History.
He said of his latest win: "If happiness is usually the size of a tennis ball, my feelings are the size of Australia.
"Blue Peter is a genuine stamp of approval and because children themselves do the voting, there's something very real about this win – it actually feels like a pat on the back from the readership themselves."
The programme's editor Ewan Vinnicombe, who also chaired the judging panel said: "Tony Robinson's Weird World Of Wonders: WWII is a worthy winner of the best book with facts. It's witty, clever and gives the reader an insight into an important historical event."
