S. A. Shelley: For those of you too young to remember, in the late nineties and early naughts (naughties?), there was a super major company called Enron. Enron was a darling of Wall Street and was hugely profitable in trading energy. It was an inventive company, too, in that it developed things such as weather derivatives and dubious accounting schemes. But it was mostly a scam, a fraud undertaken on a massive scale. The company eventually collapsed, and from time to time in Houston, you can still meet a former Enron employee in a pub who, after a beer or two, will tell you wonderful tales of excess at that company.
