Reminds me of the time I worked for one company and prior to going public, we called in some Sarbanes-Oxley consultants to vet us. After a thorough SOX compliance effort (which was ridiculous - one recommendation was "print out all source code and file it"), I showed up one day and an accountant in the corner had disappeared.

Seems that he had a gambling problem, but was allowed to both cut checks and sign them (fall into the GAAP). He embezzled, IIRC, close to one million dollars and was only found due to the SOX compliance effort.
