Gonna try and combat the negativity of the other thread with this I'll start: Tim Minchin Matt Mulholland (not famous, but he's on the youtubes and very funny, look him up) Tim Vine
I don't find any consistently hilarious but these are the ones that make me laugh the most. Kevin Bridges Sean Lock David Mitchell Bob Mortimer
Sarah Silverman by a long way. The most offensive too, if you let it offend you. Lee Mack belongs on the other thread.
Recently I've been watching a lot of Louis CK and some bits by David Kay Always love watching Stewart Lee too
Mark Thomas is the comedian i most enjoy , might not always be laugh out loud funny, mainly because he doesnt do mainstream comedy "knob and fanny" jokes
Naturally funny stand ups - the ones that don't need to try to be funny - you just laugh as soon as you see them Jackie Mason Jack Benney Frankie Howard Alan Carr Bernard Manning Peter Cooke + Dudley Eddie Izzard Peter Kay Chris Rock Johney Vegas
