the finite monkeys theorem is a corollary to the infinite monkeys theorem which states that if you have a finite number of monkeys in a room with a finite number of typewriters, after a finite amount of time, the room will smell awful and you'll have a lot of pieces of paper that look like this:

in other words.. a finite number of monkeys and a finite amount of time is basically useless, as far as producing great works of literature are concerned.
