I remembered the bit about "So doff your hat I pray" and "Sod off..sod off...sod off") but very little else, so thanks to Dave Barns, etc, for supplying the rest.

The Two Ronnies are actually due to make a comeback on British TV (BBC) soon, which is either very brave or very stupid considering it is many years (?25 or more) since they appeared together and Ronnie Barker retired some years ago, also he must be at least must be 70 or so. However the very best of luck to them from me (and from him).

To Hipflask Andy, the sketch you refer to was about "Learning Swedish" (as RB said, "We are going to have a Swedish lesson, but this one is different - it is in Norwegian"). They used single letters to represent words (English words of course), which appeared on the screen as well as being spoken somewhat slowly by Ronnie Barker and Ronnie Corbett.

Following a pictorial introduction, eg " C T " (picture of a city), P T (picture of a crying child being comforted, ie PITY), there was a picture of a womans cleavage, which Ronnie Barker as the Swedish professor type introduced by saying "And here (slight pause) we have another picture for you" as "T T " came up on the screen. The main scene was in a restuarant with Ronnie Corbett as the customer and Ronnie Barker as the waiter.

The main part started by RC saying "F U N E X" (HAVE YOU ANY EGGS?), followed by RB saying " S V F X " (YES, WE HAVE EGGS), "F U N E M" (HAVE YOU ANY HAM?), "S V F M" (YES, WE HAVE HAM), "F U N E T" (HAVE YOU ANY TEA?), "S V F T" (YES, WE HAVE TEA), THEN "L F X M N T" (I'll have Eggs, Ham and Tea)- not quite so sure about some of the last phrase, though it did end " X M N T". There was probably more, and it was funnier than it sounded on the page. I think Ronnie Barker as the waiter had a hilarious haircut (this probably gave rise to the expression "the lunatic fringe"). This however might have been in another restaurant scene with RC again as the customer (this time with his wife) and RB again as the waiter. Or perhaps both. The latter was in a Resturant where everything served was to do with Rook (a bird of the Crow family), such as "Rook and Raspberry Ripple" (Ice-cream), etc. The only joke I can remember was when RC said to RB something like "This is certainly not the place to come to do if you don't like Rook", whereupon RB said "Actually it is". RC: "Why?". RB; "Because we serve bloody awful Rook, that's why, old, tough and stringy".

Seem to be experiencing slight thread creep again (this sounds like a problem Ronnie Corbett might have experienced with his colourful pullovers which he wore when pioneering "sit down comedy"), but I can't really add anything to the Bold Sir John saga. Why were knights of Old always Bold (perhaps it was a misprint for Bald?), or maybe because it rhymes with Bold. As someone once said, they were always looking for a damsel to distress.
