Best comedy ever (well, apart from Fawlty Towers: I'm talking in recent years) has to be The League of Gentlemen (series 1 and 2). Absolute genius if at times a wee bit disturbed.
I've just watched the free DVD of An Audience With Billy Connolly.
Now, I've seen it before and it might be the drink, but FFS I nearly pished masel' and mostly, I knew what was coming next...
