@jwildeboer Recall that BWK coined name Unix (and not as AT&T said, to be one where Multics was many, but as Multics without b*lls), so joking was early. Another joke: BWK was an associate editor for Prentice-Hall and once bugged me to write a book, saying you don't make money, but people think you know something. I suspect "the C Programming Language" has done $OK. Finally, here's BWK's oral history I got for #computerhistorymuseumhttps://www.computerhistory.org/collections/catalog/102740170
