well, i guess if you break it down into "all of the words in shakespeare, and not "all of shakespeare." meaning that just the words that appear in the works of shakespeare would be typed, but you would not end up with a typed version of hamlet, merchant of venice, midsummer nights dream, romeo and juliet, robin hood, superman, and teletubbies. if all of the monkeys were just pushing random keys constantly, and not just slamming away on the keyboard, i suppose that one million monkeys on one million typewriters for a million years would produce all of the words that occur in shakespearian literature.
