Nature Nuts with Julian Clary (UTV, 7pm)
Despite building a career on risque double entendres, Julian Clary is now a children’s author, believe it or not.
And the camp comedian has now turned his attention not only to junior bookworms, but also earthworms, and other creatures in our backyards and beyond.
After visiting a ’Hedgehog Hosprickal’ and meeting an otter fancier (who said he’d given up innuendo?!) last week, in episode two, the host embarks on a trip to the Farne Islands with GP Dr Ben Burville.
Here, notoriously outrageous dresser Julian undergoes a costume change, swapping his showbiz sequins for a decidedly less glamorous wetsuit.
However, it’s worth it to swim with the largest carnivorous mammal in the UK, an experience that certainly gets the star’s seal of approval.
Plus there are trips to Northwich in Cheshire, Herne Bay in Kent, and last but not least, the presenter’s very own home in Kent.
