TV shows: I've developed quite the taste for UK comedy panel shows. QI, Mock The Week, 8 Out Of 10 Cats, Would I Lie To You, Have I Got News For You, Never Mind The Buzzcocks, quite a few others. Finding decent torrents for all of them is ever so much fun, but I got every single episode of the first four some time ago.
Standup comedy: The UK scene is going through one hell of a boom :D Too many to list here. If you got a Top 50 UK Comics list together, I'd probably love love love the lot. Except Michael McIntyre and Peter Kay. I find them as funny as bowel cancer. But what better way to point out the completely subjective nature of a good bit of standup by noting the packed stadiums of people who love them? Each to their own, I say.
