if you give infinite monkeys an infinite amount of time and an infinite number of pianos they will certainly eventually play the 9th symphony with 100% accuracy.

Just remember that infinite is a lot.

It also applies to parrallel universes. If space is infinite, then eventually we will come across a universe exactly the same as our own.

who the hecks ed??!?!!? does that mean if you give 1 monkey 1 piano and 1 hours, they would play 'Twinkle Little Star' in 10% accuracy?

That totally makes sense to me ;)!
