I've used this simple little trick before to remove a stubborn crank bolt, and it works like a charm.
No need to get under the car, no need for fancy tools.
Looks like I'm not the only one who knows this trick:

Cool trick.

It works well, the starter motor exerts more torque than any hand or air tool you could use.
Make sure you get the socket seated square against the bolt, and if you can, turn the engine over clockwise by hand to put a pre-load on the breaker bar. This will help to prevent the socket from popping off the bolt head, and possibly rounding it out.
