Roseanne and Tom Arnold bared their fists -- well, their tongues, actually -- last Thursday on Howard Stern's radio show. The shock jock reunited the two ex-spouses (whose divorce was bitter), with Roseanne in the studio and Tom on the phone. She accused Tom of womanizing, and he called her a "perennial victim." "OK," Arnold said in frustration, "I took all your money, and I ruined your career." "YOU ruined your career," Roseanne shot back. "I'm still working." Roseanne later asked Stern to appear on her TV talk show, which has been flagging in the ratings. Howard said no: "I'm too famous."
