The four horseman

Never ever in a month of Sundays has this ever happened before. 

Both cats on my knee, at the same time, touching furs, with no growls at all. Unbloodyheardof. 
No idea if I have or have not used the oxford comma there because I don't know what it is even after googling. And if I ever do use it, it'll be by accident. 
Language is amazing and I know punctuation can change the meaning of written sentences, but I'm one of those people who doesn't really give a monkeys.
