Man I just love the TV and radio shows that come out of the UK. So funny and off the wall. Being a Canadian I get some of the shows rebroadcast on the CBC, but Netflix has really opened up the options. Recommended by yours truly:
 
Misfits, Still Game, Danger 5, Red Dwarf, Old Harry's Game, Father Ted and so on.
 
For folks in the UK these are probably all really old repeats, but for me it's all new. I've also watched a couple TV series that I thought were American but turned out to originally come from the UK. Life On Mars is a good example.
 
Anyone know of anything else I should be looking out for?

I have always loved the English sense of humor.

Loads, but a few of my favourites...
 
Detectorists (for me, the best British comedy in the last couple of years)
W1A (brilliant spoof fly-on-the-wall documentary about the BBC)
Twenty-Twelve (predecessor of the above, about the London Olympics)
Extras
The Office
Peep Show
Blackadder
Men Behaving badly
Auf Weidersehen, Pet
The Inbetweeners
Black Books
Cradle to Grave (new series, really enjoying it so far)
 
 
 

If you like classic British humor then you'll probably love the books of P.G. Wodehouse, the father of modern British comedy. The books he wrote at his peak (1930's - 1950's) are perhaps the funniest writing in the English language. Virtually every form of British comedy since then, from the classic kid's comics The Beano & The Dandy to classic British sitcoms like Fawlty Towers and Blackadder to the hilarious adult comic Viz, has its roots in Wodehouse in some way. 
 
Wodehouse had a command of the English language and a turn of phrase like no other. His characters were hilarious and his plots delightfully silly. I can read a Wodehouse book and then happily re-read it 5 or 6 months later, every page is a comic pleasure. I'm currently on my 7th reading of Uncle Fred In The Springtime and will probably get started on The Code Of The Woosters after that for what must be at least the 10th time. Never get bored of them. Any time I'm feeling down, or stressed out, I know I can pick up one of the Blandings Castle or Jeeves and Wooster books and instantly be transported into a wonderful world in which nothing bad ever happens except young men inadvertently becoming engaged to women with intimidating profiles and portly Dukes who express themselves with their mustaches plotting to steal their host's prize pigs.

Good stuff. I didn't think it was going work, but they've got it spot on.

Blackadder

The Inbetweeners
 

 
Copious +1's
 
I'll add:

• The Comic Strip Presents
• Dad's Army
• The Fall And Rise Of Reginald Perrin (the original with Leonard Rossiter of course, not that recent abortion with Martin Clunes)
• Fawlty Towers
• The New Statesman
• Not The Nine O'clock News
• Ripping Yarns
• The Young Ones
• Spitting Image
• The Fast Show
• Bottom

And possible my favourite of all...

• Father Ted

I like Fawlty Towers
 
I also liked the first season of Spy

The Father Ted Christmas special is perhaps one of the best Christmas specials of all time.

I love Peep show, perhaps because I have known all 3 characters in real life in one form or another - Mark, Jez and Superhans. Mind that Sophie is a real beatch. I still laugh thinking about Superhans wanting to open a pub called "Free The Pedos."

Forgot one of my all-time faves;
 
'I'm Alan Partridge'
 
2 sublime series and an excellent movie.
 
Also love 'The Trip' with Coogan and Rob Brydon.

i was just about to say alan partridge too :) That was just so good!
