How Fast Can a Black Hole Spin?

The only limit on how fast a black hole could spin is the speed of light. Nobody knows what would happen if you broke that rule. Would it actually crack open the black hole? Would you go to physics jail? In case Old Ballet teacher come and scold you, let's find out. If you would be willing to add your voice to this group of volunteers, please don't be shy.
