In a hilarious double-play, comedian Jon Stewart last night hammered Lenny “Nails” Dykstra, a former Mets centerfielder turned financial-advisor-in-bankruptcy, and then tagged TV financial personality Jim Cramer with a jarring comedic blast.

Stewart began a segment on last night’s show by focusing on the irony of the bankruptcy filing by Dykstra, who touted himself in recent years as a successful investment advisor and was profiled in 2008 as a “financial whiz kid” on the HBO program Real Sports. Dykstra, who told a Real Sports reporter that he did not read books because it was bad for his eyes, reportedly was sued by 20 creditors by the time he filed for bankruptcy on July 7.

Stewart revived his public humiliation of Cramer by playing an interview of Cramer on the HBO show in which he hails former Mets hero Dykstra’s as a brilliant financial advisor, “one of the great ones in this business.”

The irony of the baseball legend turned stock-guru’s misfortune provided Stewart with great material. Dykstra, 46, became a New York Mets hero for hitting a walk-off home run in Game 3 of the 1986 World Series, when the Mets defeated the Boston Red Sox in seven games to win one of baseball’s most memorable World Championship Series.

Cramer, the extremely energetic host of CNBC’s “Mad Money” and founder of TheStreet.com, is a former hedge fund manager. Prone to hyperbolic rants, Cramer was the subject on March 4 and March 9 of scathingly funny blasts by Stewart. Stewart, the popular host of Comedy Central’s “The Daily Show,” assembled a string of video clips in which the self-proclaimed “infotainer” of finance made glaringly wrong investment predictions. Stewart wrecked any credibility Cramer might have had in the financial media by showing Cramer urging stock investors to “be buying things and accept that they’re overvalued, but accept that they’re going to keep going higher” a few months before the global financial crisis caused a stock market collapse. Stewart and Cramer’s public showdown became famous and then faded—until last night.
