Laudator Temporis Acti

Attributed to Robert Wilensky:

We've all heard that a million monkeys banging on a million typewriters will eventually reproduce the entire works of Shakespeare. Now, thanks to the Internet, we know this is not true.

Thoth, the Egyptian god of writing, was sometimes represented as a baboon.

Cf. also:

• Cicero, On the Nature of the Gods 2.37 (tr. C.D. Yonge): "He who believes this may as well believe that if a great quantity of the one-and-twenty letters, composed either of gold or any other matter, were thrown upon the ground, they would fall into such order as legibly to form the Annals of Ennius. I doubt whether fortune could make a single verse of them."
  
• Montaigne, Apology for Raymond Sebond (tr. Donald M. Frame): "If the atoms have, by chance, formed so many sorts of figures, why have they never happened to meet to make a house, or a shoe? Why do we not believe likewise that an infinite number of Greek letters scattered about the place would be capable of forming the web of the Iliad?"
