Douglas Adams knew John Cleese and Eleanor Bron through his connections with Monty Python and Cambridge Footlights. On learning that both would be working in BBC Television Centre on the day the art gallery scenes were to be recorded, he persuaded them to make a cameo appearance in a short scene written for "two Englishmen". Cleese and Bron agreed on the condition that there be no pre-publicity regarding their appearance; Cleese wanted them to be credited as "Helen Swanetsky" and "Kim Bread" but the BBC declined, failing to see the joke. During recording, Cleese and Baker also recorded two short comedy skits for the BBC Christmas tape. Bron later returned to play Kara in Revelation of the Daleks. She also played Ileana de Santos in the audio play Loups-Garoux.
The British term "failed to see the joke" should probably be translated for Americans to "failed to see any humor". It is not a reference to having to understand the logic, get the irony, sneer with them at the sarcasm or cynicism, etc, because there often isn't any of the above, especially when dealing with loonies.
I would think he chose Woody because of the reference to the male anatomy, kind of like full monty and python. But whatever. I would have laughed myself silly thinking it was something dirty, but that's just me. I'm kinda weird that way.
Wasn't Kim Bread the name of a minor character on Magic Christian, or somehow. I don't know why I'm linking it to him and a film he was in earlier, but then again, when you think about it, Skim Milk, Kim Bread. I don't know. Just an unnatural sounding name and therefore, funny. Kim Jones, you wouldn't blink, but Kim Bread, you think, that's an awkward kind of name.
Haven't had any in a while, but I like bread with tons of grains in it, the more bird-seed encrusted it appears the more I like it. And dark breads. And the aforementioned Kim Bread, of course.
