Fawlty Towers went for 2 seasons of 6 episodes, made several years apart. The BBC played several re-runs of season 1, becoming more popular each time, without really knowing if Cleese and Booth were actually DOING a second series!
Cleese was married to Connie Booth at the time (Polly the maid) but their marriage broke up during the period between the 2 series and once they finished the second series both went on to other things. Cleese was making a lot of customer service and staff training films around this time (remember the ads anyone?) and Connie Booth soon stopped doing anything in public and became something of a recluse, she NEVER talks about Fawlty Towers anymore which is sad seeing as she helped CREATE it.
Blackadder (my all time favorite) ran for the 4 seasons but Ben Elton started writing for it from season 2. The humor is very recognisable as Elton from this point.. "as cunning as a cunning fox that's just been made professor of cunning at Oxford", "It's the most pointless book since 'how to speak French' was translated into French". The quotes from Blackadder are some of the funniest oneliners I think I've heard on tv, and I've watched A LOT of tv!!
Richard Curtis and Ben Elton also wrote The Young Ones (another 2 series of 6 episodes each, and another show called "The thin blue line", I loved this show! It's another Rowan Atkinson series... GO THE BBC!!
aaaahhhh, I loooove tv...

You must be my twin..or im yours.
Wacthed the cleese customer service ads aaaaages ago, can see where ING got the Billy Connely idea
Couldnt agree more with the blackadder comments. His insults to Bladrick & Percy are brilliant.
Some of my fave scenes
Edmund: Right. Now all we have to do is fill in this MP application form. Name: (with Baldrick) `Baldrick'. First name...?
Baldrick: Er, I'm not sure.
Edmund: Well, you must have some idea...
Baldrick: Well, it might be `Sod off'.
Edmund: What?
Baldrick: Well, when I used to play in the gutter, I used to say to the other snipes, "Hello, my name's Baldrick," and they'd say, "Yes, we know. Sod off, Baldrick."
Edmund: All right, right right right right, `Mr. S. Baldrick'. Now; distinguishing features... `None'.
Baldrick: Well, I've got this big growth in the middle of my face.
Edmund: That's your nose, Baldrick.
Edmund: Ivor Jest-ye-not-madam Biggun...
Vincent Hanna: (cuts) Standing-At-The-Back-Dressed-Stupidly-And-Looking-Stupid Party...
Edmund: No votes.
