I adore Alan Davies, especially in the series "Jonathan Creek" and in the mini-series "Bob and Rose (about a gay man who falls for a woman)

I also love Bill Bailey, who does quite a lot of stand up, as well as other panel shows (plus "Black Books," which is a fantastic comedy series...and I *hate* sitcoms *g*)

There's also a bit of QI RPF on the yuletide archive (under RPF: Quite Interesting), if you're into that.
