Roseanne Barr's husband wants a gag to work - one from a court, not from her hit TV show.

Tom Arnold filed a lawsuit Wednesday in Superior Court in Los Angeles charging that Barr's former husband and his attorney violated a court order by discussing the comic's divorce publicly.Arnold said ex-husband William Pentland and his attorney, palimony lawyer Marvin Mitchelson, discussed the divorce on the "Donahue" show in November.

Arnold's lawyer, Martin Singer, asked a judge to sentence Mitchelson to 30 days in jail and Pentland to 15 days for contempt of court. Singer said Mitchelson "has engaged in a widespread publicity campaign to try to maliciously disparage and defame Tom Arnold in direct violation of the order."

Mitchelson said he would file a countersuit, saying it was Barr who called into "Donahue" and discussed the divorce. She also made disparaging remarks about the divorce, he said.
