This is my list in no particular order.

Twin Peaks
The Prisoner
The Avengers
Danger Man
Fawlty Towers (should this one be taken as read in everybody's list?)
Monty Pythons Flying Circus
Hancock's Half Hour
The Phil Silvers Show (Bilko)
Top Cat (or "The Boss Cat" as I think it has to be called in UK)
The Magic Roundabout (with the Thompson? voiceovers-hilarious! And starring the one and only Dougal!)
The Likely Lads (and Whatever Happened to the Likely Lads)
That Was the Week that Was
The Frost Report
When the Boat Comes In
Auf Wiedersehen Pet
The Telegoons
Only Fools and Horses
Not Only ... But Also ...
The Q series (Spike Milligan)
The Two Ronnies
Porridge
Open All Hours
Dad's Army
The Ascent of Man

From childhood/teenage years there is also Cheyenne, The Lone Ranger, Wagon Train, Bonanza, Man from UNCLE and United! (a soap about a football team). Loved them at the time but doubt if I would enjoy any of them now.

Here's mine narrowed down to top 5, including explanations.

1) All in the Family/ MASH (tie) best American comedies ever.

2) Survivor (#1) - simply untouchable, an idea who's time has come.

3) Fawlty Towers - the best British comedy ever

4) Twilight Zone - story telling at it's best

5) The Sopranos - again, the best thing going today!!!!!
