I second whoever said Bill Bailey rules.
And Russell Brand is shite.
Probably my favourite comedian is Frankie Boyle though.

Bill Hicks is the man. His humor is so off-color, but so awesome.
"What the fuck is with Christians and crosses? You think when Jesus comes back from the dead he ever wants to see a fucking cross? That would be like going up to Jackie Onassis with a rifle pendant on and saying 'Just thinking of John, Jackie.'"
