Though the Newark Star-Ledger already wrote about this case 5 days ago, time stands still where the New York Times’ David Kocieniewski is concerned.

For more than a decade, Sgt. John Feder (above, right) managed to keep the depravity in his life neatly compartmentalized.

By day, he chased miscreant police officers, working as an internal affairs investigator for the Police Department in West Orange, N.J. At night, he assumed the stage name Club Soda Kenny and delivered a raunchy comedy act. He has appeared on the Opie & Anthony radio program and even with the bard of bathroom humor, Andrew Dice Clay.

But late last month, when a CD of Sergeant Feder’s act was mailed to police officials and members of the City Council, the laughter stopped. They suspended him last week and filed departmental charges that could cost him his $88,000-a-year job and his pension.

Police supervisors said they had no idea that Sergeant Feder, who has a decorated 22-year career on the force, spent nights in front of audiences joking about bestiality and bladder control.

Sergeant Feder got his start in comedy by working as a bodyguard for Mr. Clay, the comedian who became wildly successful by making brash sexual references, including many that gay activists considered homophobic, and with unsparing diatribes about the physiques of female audience members.

Mr. Clay would often invite Sergeant Feder onstage to deliver a few jokes. His countless requests to “get me a club soda, Kenny,” led to Sergeant Feder’s stage name. The sergeant took a brief leave of absence more than a decade ago to join Mr. Clay’s national tour and, after returning to the force, began making occasional appearances at local comedy clubs and more recently on the XM Satellite Radio program “Opie & Anthony.”

Mr. Bergrin said that Sergeant Feder had never received complaints from any comedy club patrons. He said he suspected that the CD was sent to police officials as an act of retaliation by a rogue police officer Sergeant Feder had investigated. “It’s hard to imagine who else might do such a thing,” he said.

Police officials say they are still not sure who sent the CD. But once they heard Sergeant Feder onstage delivering punch lines about raping a bride at knifepoint, having sex with his dog and sexually molesting his own 5-year-old son, they opened an investigation that led to several departmental charges, they said. The department alleges that he used a police computer to write one of the controversial monologues. It has also charged that he violated the regulation requiring officers to notify their superiors about moonlighting.
