I couldn't agree more, Scherpschutter.....it is not often, in a comedy, that there are so many hilarious quotes, in so few episodes.
There is hardly a day that goes by, that I don't think of my 'Basil', to my wife's 'Manuel', and then come out with an appropriate quote, for the situation.
And, as for 'Manuel's' best moment in the series...it is so difficult to choose, because there were so many.....
However, the final episode, 'Basil, the Rat', comes to mind....
John Cleese as Basil Fawlty: "Manuel, it's a rat!"
Manuel: "No, no, it not a rat, it's a Siberian Hampster!"
Classic. R.I.P Mr. Sachs.
