One of the multiple times I'm overjoyed with the BBC...

No ads. Ever. Well, except for their own programs, but that doesn't really count. Which means, as I don't watch all that much TV, I have absolutely no idea what these fast food adverts entail. Which I have gathered is desirable.

Getting back on topic, I suppose that an additional problem with determining what is fictitious and what is not in regards to the UF Universe is that one (for the most part) cannot know whether the thing in question is deemed fictional or is just something our lords and masters haven't got round to crowbaring in yet.

At a guess, I'd say Rumpole Of The Bailey was fictional, due to Moose MacEchearn's calling Kaitlyn 'She Who Must Be Obeyed'. Though Rumpole might just be a famous lawyer on Hoffman. It is all but impossible to tell, and the only way to find out is to ask.
