There was an extremely genteel lady who was travelling in a train, and it so happened that sitting opposite to her there was a man who had a crucifix on his watch chain, but, in spite of this talked in a very blasphemous and horrible fashion. The lady said to him, "I am surprised, my man, in view of the emblem that you bear, I hear you speaking in this manner". And he said, "Lor, Ma'am, that ain't Christ, that's the other bloke that died by him".

If you can get your hands on the book, it is worth reading. It is available on Amazon.in and costs Rs. 6.1432.44 (hardcover) & Rs. 4,003.27 (paperback). Pretty costly. Can't afford to buy books these days. I wonder if there is a Kindle edition available. Should be relatively cheaper but still costly. I only have some excerpts from the book. One of them is about the author of the poem "The Blessed Damozel" which I will refrain from posting here.
