Behind the scenes and off the screens

Sometimes, as you're idly watching television, the mind starts to wander, and you find yourself thinking about the people on the screen. Who are these characters? What are they really like when the cameras aren't watching?
Take, for example, everyone's favourite daytime television couple, Richard Madeley and Judy Finnigan. For years now, first on This Morning and subsequently on their eponymous Channel 4 show, they have been interviewing guests and presenting a united front. However, the most interesting thing about this pair is their own interaction: before the reality show invasion, they were about the only on-screen insight into the petty spats and everyday irritations of married life. Richard is a know-it-all - he has been everywhere their callers live, done everything a guest has done, knows all about an expert's subject. Judy is quite clearly often highly irritated by this, especially when he veers into discussing aspects of their private life. Judy has her "illnesses" and "contact lens mishaps", and relies on Richard to cover for her.
But other than this, what do we really know about them? We know that Richard isn't a shoplifter, that Judy doesn't match her underwear to her outfits, we know that she is older and they met at work (supposedly her first words to him were "I'm your mummy" - now that's an unsettling image...), and we know about their children.
The gaps in concrete knowledge we can fill with gossip and speculation. What keeps them going, other than an obvious desire to avoid career suicide? Anyone who has seen them on TV will realise that there is an obvious affection between them, though on Judy's part it often seems like the love of a mother for an errant son (yeuch, there it is again...). One suspects that Judy has to keep a firm control over Richard: maybe this is part of the appeal of the relationship for both of them.
I'm sure he's let off the leash occasionally though, and what he might do then to amuse himself I simply couldn't imagine...
