Is Dorothy Byrne the bastard offspring of Dylan the Rabbit?

Justin Webb seems like a decent enough cove and I, for one, won't stoop so low as to attempt to make comic mileage out of his admission that he is the lovechild of the 1970s newsreader Peter Woods. 

But pondering whether there's a format to be made out of it (and oodles of lovely money) is quite another matter. 

I'm thinking about a twist on the genealogy formats so prevalent in today's schedules, in which a member of the public or minor public figure - such as a Radio 4 news presenter - goes back through their family tree to discover which priapic or sexually incontinent celebrity is the joker in their gene pool. Who Do You Think Your Star maybe? 

Justin's confession has also got me speculating on which other stars of the modern broadcasting firmament may be related to some of the dodgier icons of the late 20th Century.

Is George Entwistle the product of a torrid one-night stand between The Who’s legendary bassist and a particularly myopic librarian from Stevenage called Vera?

Was David Abraham’s mullet the result of an experiment in the Timotei Hair Care Lab to examine the growth properties of elephant dung mixed with whipped cream and nitrous oxide using hair samples provided by Kevin Keegan and Jeremy Beadle?

Surely Jeff Ford's genes don’t lie. He's clearly the offspring of GLC firebrand, Red Ken, isn't he?

Does Dorothy Byrne provide the final proof that there was more than meets the eye to the onscreen chemistry between Dylan the Rabbit and Florence from The Magic Roundabout? And is Janice Hadlow the missing genetic link between Jane from Roddy, Jane and Freddy and George from Rainbow?

Was Natalka Znak all that was left after an explosion on the Scrabble production line in a Hasbro factory in Wisconsin?

Is Ben Stephenson in any way related to Mr Bean?

Does the existence of Richard Woolfe raise questions about exactly what Dale Winton’s mother got up to in the 1970s?

And is there the slightest truth in the rumour that that blond reprobate Kevin Lygo is the legitimate second son of former Vice Naval Chief of Staff Admiral Sir Raymond Lygo KCB?

Actually... on second thoughts. No. Sorry. That last one’s just totally implausible…

Who's the daddy?

Ben or Bean?
