Frankie Boyle
Jason Manford
Ricky Gervais
Michael McIntyre
Frank Skinner - Even though he rarely does stand up these days. Some of his stand-up stuff is excellent.
Saw The Big Yin in concert twice a few years back and he was hilarious - I have never laughed so much in all my life - my sides hurt so much I just wanted him to stop.
Barker for his comic creations (Arkwright, Fletcher etc) and his Two Ronnies stuff
Cooper for being so original and appearing genuinely pissed most of the time (which, I gather, he was) but ultimately VERY funny.
