No, I'm saying it's not just improbable (if it were improbable, then yes, it would happen), I'm saying it's impossible because of behavior.

As a small example, let's say you wanted to type the ABC's. However, every time you typed, your finger slid to press the key next to it as well. Then, no matter how many times you tried, you would never be able to type the ABC's. That's an exaggerated example of what I believe the monkeys would do. They simply would not be able to type letters at random. The way they work, they would be forced to mush buttons that do not allow for whole words.

If there was another scenario where there were about 30 boxes (one for each letter and any punctuation needed), and the monkey had to get a banana from one of the boxes, and that is what 'typed' the script, then yes, an infinite number of monkeys would be able to type Shakespeare. But because it's a typewriter, I don't think even an infinite amount would be able to.
