LTCM is a classic, ZZZZ Best is hilarious, Bernie Madoff is obviously the king. Everything that came to a head in 2008 doesn't get the fire in my loins going because there's just too many players and the build up is too long.
South Sea Company is a good old one. Same with Mississippi Company from John Law. BCCI has a nice number of aspects to it with oil sheiks and drug cartels. Allied Crude Vegetable Oil is funny. So is how Barings collapsed. Pemex dumping oil into the gulf and then going "lol sovereign immunity" is solid.
But my top favorite is still Enron. A company that nobody knows how they make any income and doesn't really sell anything and fails to make a deal with Blockbuster Video that it counts as an asset and all sorts of other stuff, that also takes out Arthur Andersen with it for trying to cover up. While all the top names but Kenneth Lay are bailing out, and they're faking offices by moving employees around. And they make all sorts of front corporations which buy things from Enron using Enron stock as collateral. And then Enron goes "hey, we're good" posting 750% increase in revenues and everybody in finance is like "welp, alright, buy buy buy!"
Plus they named some of their fraud schemes JEDI and after velociraptors in Jurassic Park. And tried to trade weather.
Also, Ken Lay pulled a Clay Bennett, when the two companies that merged to form Enron he promised they wouldn't move out of Omaha. And he instantly moved them to Houston.
Also, Lou Pai.
My favorite part is still the whole "what do they sell to make money? I dunno, lets invest!" part. And another company still wanted to buy them in late 2001.
