I got the bus to Dundee today on my way to watch United (they won 1-0, you'll all be pleased to know). Anyway, there was an elderly man and woman sitting in front of me---I think they were neighbours, rather than a couple---and they were having a conversation about holidays. The following is almost word for word....
Her: I've always wanted to see the Mona Lisa.
Him: Really?
Her: Yeah, it looks fantastic but I've only seen pictures of it. Princess Diana was there, sitting on her own by the water. It just looked so beautiful.
Him: Princess Diana by the water? Do you mean the Taj Mahal?
Her: Yes, the Taj Mahal. What did I say?
Him: The Mona Lisa.
Her: Oh, what an idiot! I meant the Taj Mahal, not that painting!
There was a slight pause.
Her: It IS a painting, isn't it?
When I got off the bus, I almost thanked her for my next Dennis script.
