If you watch Strictly, you’ll find The Charleston is a staple element and every couple has to perform it during the series.
As for the Napoleonic madman, I seem to remember the figure being used as a shorthand in cartoons, animated cartoons and sketch shows from the sixties through the early seventies.
While living in London, I was struck by how many people were walking around aimlessly having conversations with themselves. Now we have mobile phones and we see people chatting on the phone in the street all the time. The question is,,,, how often is there no-one at the other end listening?
I suppose if you were scared in the street, pretending to chat to the speaking clock on your mobile might put a threatening person off from approaching you, and that wouldn't make you mad. If however you genuinely believed the speaking clock was conversing with you, then you have a problem.
