The pantheon of edgy CEO’s includes TYCO’s Dennis Koslowski whose sales tax dodge on artwork he purchased mirrored a fast and loose corporate stewardship that resulted in jail time.

Keep an eye on those edgy acheivers, even if (maybe especially if), their foot seems never to come off the accelerator in pursuit of outsized results.
