Is there a more feelgood show on the box than BBC2's Springwatch? I started watching last night's show in something of a hissy fit, and ended it grinning ear to ear.
So what's so good about it? Well, there's the wildlife - I'm a bit of a birdwatcher - there's lovely Simon King's infectious enthusiasm and baseball caps, and then there's the Bill and Kate show.
That's Bill Oddie and Kate Humble, of course, and a large part of the fun is watching Oddie go off on another flight of fancy - boom, boom - talking all over Humble while she tries to link to the next film or interview.
Last night's show had a particularly classic moment when Humble asked King if there were any little ringed plovers - it's a bird - in the Cairngorms. Oddie looked incredulous. Of course you don't get little ringed plovers in the Cairngorms! D'oh! Humble might as well have asked if a whale could play the piano.
It might just be me, but Humble's smile at the end of last night's show looked more fixed than the Eurovision Song Contest.
Anyway, it's all part of the fun, and I won't have a word said against Oddie and his idiosyncratic presenting style, last night banging on about "underage sex" among barn owls.
The state of the planet means we take rather more notice of our birds and wildlife than we once did. But it is still quite a feat by BBC2 to turn it into a primetime hit TV show, now into its fourth series.
Not only that, the great thing about Springwatch is it's brilliantly simple to get involved, from blogging on the programme's message boards to sending in your own video footage, to applying for a grant to help your local wildlife. It's got public service broadcasting written through it like a stick of rock.
Which makes it even more of a shame that its scheduling will be messed around to make room for Euro 2008 footie. Let's hope someone remembers to tell the treecreepers. I love treecreepers - look at their hilariously big feet!. First Pushing Daisies, then The Apprentice, now Springwatch. Whatever next? Holby?!
Regular viewers will know that Springwatch and its seasonal offshoot, Autumnwatch - which last year was a bit of a letdown - is not all about birds, although I'm not fussed about badgers or, as I mentioned during the last series, urban foxes.
Much more fun are the ospreys, lapwings and - another classic moment from last night - the Scottish woodpecker, which pecks not on trees but metal girders on the side of telegraph polls. Fantastic!
Bring on the next two and a half weeks. It's almost enough to make me forget the annual horror show that is Big Brother is coming back. Almost.
