Having been in "I hate all Radio 4 comedy" mode for quite some time, I found myself doing actual, real-life guffaws - more than one! - at Heresy on Wednesday evening. It's quite a while since I've done this listening between 6.30 and 7pm, I must say.

There's not much at all to Heresy - it's just a series of received opinions unpicked by witty people in front of a live audience - but, somehow, this week's episode really worked. This was a lot to do with host Victoria Coren Mitchell, who delivers her tinder-dry lines with just the right amount of nonchalance. She's sharp without being nasty or egomaniacal: at certain points in this episode, she formed a sort of comedy alliance with guest Katy Brand, also on great form. Lloyd Langford, a standup, was excellent, and Grayson Perry as hilarious as ever. The person who made me laugh the most, however, was a member of the audience during a discussion about whether anyone would want to own a picture painted by Hitler. I'm not going to spoil his deadpan punchline, but, listeners, I laughed. I honestly did.

Next thing, I'll start liking Radio 2 documentaries... Or maybe not. I do find them irritating. They have great content, but the style, editing and scripts drive me doolally. Too often they come across as documentaries for simpletons, and Radio 2 listeners aren't stupid.
