>>I've only ever seen clips from any of these films but I think he does use it a lot, only he uses the rhyme as well, which isn't correct, but needs to be there for the uninitiated. For instance, "fish and chips", in RS, is "lilian and jockeys". It's sometimes an amusing mental exercise to figure out the rhyme or meaning, though the context usually gives it to you. e.g. you might ask for the above dish in a "chip shop"

>I understood all the words you wrote, other than "lilian," but I have no idea what any of it really meant! Fish? Potatoes? Lilian? Jockeys? Are you sure we are originally from the same place? <g>

Like I said, "lilian" is "fish", as in Lilian Gish, the silent era actress, and "jockeys" is "Jockey's whips", so "fish and chips".

Now try the others...
