I rewatched it all a little while ago, and I have to say that, although when they are good, they are brilliant, there is quite a lot of each show that was pretty dull stuff really.
I think it's true that almost every episode had at least one sketch that was hilarious, but that in each half hour episode only about 10 minutes could be considered exceptional. That's still a pretty good score, but I can't say it was non stop killing, as your first post seems to imply,
@BAYLOR.
We all know which of the sketches were so brilliant, and on this site we have several threads on which we are invited to highlight them. And as you say, many of them have passed into everyday language. Most noticeably Spam and the Spanish Inquisition. But this can be said of several other shows and films.
Just the other day, as I was waiting at the cashier in the supermarket, they played Hot Stuff on the tannoy, and I found myself copying the guys from the dole queue in the Full Monty. I doubt that very many of the French men and women there had any idea why I was doing it, but it would have been recognised in Blighty.
