Cramer's hearing that some people on Wall Street may be up to old tricks.
"And until Uncle Sam does something, I am on a mission, a mission to shame all who sell these lethal pieces of paper and to warn those who might by them."
At issue is the return of CDO's or collateralized debt obligations. Don't get turned off by the fancy language - Cramer says it's intended to be confusing so you'll look the other way.
"They're basically abstruse financially engineered bonds - essentially risky bets on housing, made riskier by the amount of leverage that funds use to juice their returns," Cramer explained.
"And we need to stop this travesty before we get a repeat of the 2007 to 2009 financial apocalypse," he added.
Although Cramer concedes CDO's may have a place in the world of professional investing, he feels it's just a matter of time before they make their way into individual portfolios.
And that Cramer can not abide.
