In Rants and Revelations: Art in spammer subject lines I saw something that looked like art in what I thought were random words generated by spammers. Well, JoAnne just pointed out to me that the words actually come from The Master and the Margarita by Bulgakov.
Amazing. I assume that means the spammers just grabbed some text file they found on-line and used it to generate phrases, and not that they are secretly highly literate and fans of english translations of obscure russian authors.
