1 - Fawlty Towers
I come from Torquay. It's only obligatory that I put Fawlty Towers first. But John Cleese is one of my favourite comedy actors ever. Loads of memorable scenes.
2 - Family Guy
Love it. One of the few shows on TV today I will go out of my way to watch.
3 - Will & Grace
Great, likable, funny characters. And the theme tune is funky
4 - The Royle Family
Really sad ending, but a really simple and effective comedy series.
5 - Friends
Everyone has a show they grew up watching and characters they grew to love; most 90s' kids' was Friends. Sometimes the characters Ross & Joey annoy me, because I don't like stupid humour, but Phoebe, Monica, Chandler and Rachel make up for it
6 - Only Fools and Horses
My dad's favourite show, but I remember as a child the theme tune used to make me cry

But it's obviously provided a lot of memorable sketches.
7 - Vicar of Dibley
Only so low because it's been repeated beyond belief.
8 - French & Saunders Sketch shows
Lots of hilarious scenes, somewhat spoiled by some not-so-funny ones.
9 - Extras
I haven't watched any full episodes, hence being so low, but clips I've seen on youtube have been very funny.
10 - Peep Show
Clever way of filming the sitcom, David Mitchell is brilliant.
