The feud between "The Daily Show" host Jon Stewart and investment pundit Jim Cramer is building into an all-out zinger fest. It started, in case you missed it, with this eight-minute blitz from Stewart, alleging that Cramer and other CNBC luminaries whipped Americans into a frenzy of foolish investments. "Bear Stearns is fine. ... Bear Stearns is not in trouble!" Cramer roared six days before the investment firm perished, in one of several clips Stewart mocked on his show. Now Cramer is fighting back, with help from his MSNBC brethren.
