I know many people find Michael MacIntyre a majoe irritant, but I like him - he's very funny, and I think he's probably a very nice bloke, although his relentless puppyish enthusiasm can be a bit wearing.
Lenny Henry - another lovely bloke, but only mildly amusing as a stand-up, and pure teak as a straight actor.
Peter Kay - so-so.
Katy Brand - brilliant!
Catherine Tate - ditto!
Peter Serafinowicz - passable straight actor, complete humour-free zone as a stand-up and sketch comedian.
Erica Nernie - the legends.
Laura Lanhardy - the incomparable.
The Two Ronnies - unforgettable (in a good way).
Max Miller - supposedly a legend, but I've seen ancient footage of him, and found him only intermittently amusing, and was put off by the smug, self-satisfied smile he always gave between jokes.
