An infinite number of monkeys typing randomly on an infinite number of typewriters, so long as the writing is truly random, will eventually write every novel. Once you factor in the infinite number of monkeys, every novel in existence will not only be written, it will be written an infinite number of times.

It's like saying if you had a random number generator and gave it an infinite amount of time generating 16 numbers at a time, it would eventually generate every bank card number ever an infinite number of times. Give that task to an infinite number of random number generators and they will generate every bank card number an infinite number of times instantaneously.

Come to think of it, if the tornado throws around junk completely randomly, and provided there's enough material in every junkyard to assemble a plane, the tornado will eventually assemble it. That's the power of infinity and randomness.
