i remember we were in oldham in lancashire once and a lady came in with an object. it was a little bit of a puzzle, really. but no one could exactly identify it. someone picked it up on the junk store and brought it to me and asked me if i was interested because they know i collect ivories. and i said, "yes, i'm very interested. what is it?" so they said, "i haven't a clue." so i thought, "right, i will bring it here and ask anyone here if they would know what it was." 20 years later we were in oldham again, and again the same lady turned up, this time telling us what she thought it was. this is an interesting little bit of "roadshow" history. there's arthur, of course. this is you 20 years ago - on our last visit to oldham. - that's right. and i'm playing angela rippon. arthur: you remember the occasion, do you? i do, because they didn't have a clue what it was, you see? and you've still got it and nobody knew what it was. and did you ever find out? what is it? it's used by elder chinese ladies to pass on their leisure hours. it is a chinese puzzle. - wonderful. -
