New York- He’s not crazy, he’s just stupid.

Crazy Cabbie of Howard Stern show fame admitted yesterday that blabbing on the air about not paying his taxes was a dumb move.

“I, um, was stupid,” Crazy Cabbie, whose real name is Lee Mroszak, told Brooklyn Magistrate Robert Levy.

“Didn’t file my taxes,” he added. “Made a mistake. Talked about it on the radio, made a flippant comment and it bit me in the a–. Excuse my French.”

Mroszak, 35, probably should have known that among the radio shock jock’s millions of listeners were Internal Revenue Service investigators.

After a little checking, the investigators learned that Mroszak had not filed tax returns for the years 2000 to 2003.

Assistant U.S. Attorney Jeff Goldberg estimated that Mroszak beat the IRS out of somewhere between $80,000 and $200,000 in taxable income during that period.

Yesterday, Mroszak struggled to understand the judge’s explanation of the federal sentencing guideline system. Mroszak faces less than a year in prison and a $25,000 fine, but the guidelines may soon be declared unconstitutional by the U.S. Supreme Court, the judge said.

“I grew up in the street, not in law school,” Mroszak told the judge. “If the Supreme Court comes out tomorrow and says, ‘Hey this and that,’ I’m not covered. I get it.”

“You probably understand it better than most people,” the judge replied with a smile.

The heavily tattooed member of Stern’s radio “wack pack” is a former Army paratrooper and has openly discussed on the air that he suffers from a bipolar disorder.
