The man who memorably called Goldman Sachs (NYSE: GS) a "great vampire squid wrapped around the face of humanity relentlessly jamming its blood funnel into anything that smells like money" continues his assault on the gilded bank.

As part of that effort, Matt Taibbi has come up with another zinger of a metaphor: "Defenders of Goldman have been quick to insist that while the bank may have had a few ethical slips here and there, its only real offense was being too good at making money. We now know, unequivocally, that this is bullshit. Goldman isn't a pudgy housewife who broke her diet with a few Nilla Wafers between meals - it's an advanced-stage, 1,100-pound medical emergency who hasn't left his apartment in six years, and is found by paramedics buried up to his eyes in cupcake wrappers and pizza boxes."

I'm not sure "an advanced-stage, 1,100-pound medical emergency ..." is as memorable as "vampire squid," but he's certainly trying.

His point is that the culture of fraud is endemic at the firm; it simply can't stop gorging. Unsurprisingly, Taibbi thinks the Justice Department should act quickly to charge top executives including, Lloyd Blankfein, Daniel Sparks, David Viniar and Thomas Montag with perjury at least.

My sense remains that this is still a long shot. But it's always hard to predict what the prosecutors will do. The issue is uncomfortable and nobody knows how long it will hover over the company.
