Bear said: "Marmaduke is working in a butcher's in North Wales at the moment. He's in his year off. He loves it. He comes home with good cuts of meat. 'But I know he loves the community there. He's done it up in North Wales quite a bit, Well, he comes back, he goes, 'look what I've got.'

“And he is always telling us, we're getting the wrong stuff. 'You want to get this stuff because it's cheaper, but the quality is great. Everyone just buys ribeyes and sirloin and filet, when actually you want the flank, the shin, and ideally the testicles - the beef testicles.' Asked how to prepare them before chewing, Bear reacted: 'Well you probably want to fry them up with butter.'

The 50-year-old star made his confession to radio hosty, who reacted: "Even when you're off, you're on’, to which a laughing Bear responded, “That's right!" The father-of-three revealed that his middle son is hooked on his part time job: "He has got a plastic scabbard for his knives. He got it off for eight quid."

The also revealed that his kids loved being connected to his screen antics of munching on insects, dead animals and vegetation. His sons even urged their father to feed them maggots so that they could be involved in his 40th birthday celebrations.

He recalled, “Because they were obviously smaller then, they wanted to be involved in the party in some way. We had all our best friends in the garden and I wanted to do some games and forfeits, and they didn't want to miss out on this. So I said, look - the treat is, before going to bed, you can each have a maggot."

Bear, who was chatting to Dermot to promote his new book You Decide Your Own Adventure, also said that he feels even can have its benefits. "Sometimes, those are the best adventures. It can be in the backyard. It’s the simple things, isn't it? What do they say? Sum up parenting in three words. Example, example, example. Get outside and do it together.

"And I think often you don't need to come down to a kid's level to say, we're going to play a little game or whatever." Actually kids just want to hang out with you and go and do stuff and go for a walk, a bike ride.

"The fun is there inherently. So simple things together, try and lead by example. Live your life with an adventure state of mind, how you approach everything. Work, relationships, friendships, adventure, state of mind. Let that lead."
