"Anonymous should be ignored by all Shakespeare lovers" by Francis Phillips at the Catholic Herald
"Shakespeare authorship fantasists don't understand how plays actually get written" by Allan Massie at The Telegraph

Jeeves: "I cannot recall his exact words, sir, but he drew a comparison between your mentality and that of a cuckoo."
Wooster: "A cuckoo, eh?"
Jeeves: "Yes, sir. To the bird's advantage."
