its normal, and it doesn't just happen to politicians, i believe that when the news broke about Angus Deayton's shannanigans, he once hosted the show, he came in for some very naughty comments from Hislop and Merton, i also think they once likened John Prescott to a lump of lard, or some such jape, i like the show, though i am sure one of these days someone will totally over step the mark, and by the way, Farage didn't have to go on it, he would know what kind of show it is.
