It’s hard to know when this sort of children’s television (EdI placed the apostrophe there after some deliberation, I assume only one child ever watched this, but then I had a further dilemma because children is plural. So I was going to suggest two childs = a children. And two children watched this. And then I realised that because children is a collective noun the apostrophe belongs there anyway) was actually appealing.
You have to do a little bit of source criticism on this to figure out how much of the craziness is attributable to the original, and not to the editors, but if anybody knows anything about the origins of this ‘ere show, I’d love to hear about it.
