A corrections spokesman this week confirmed Limbaugh has been a good boy and that the drug tests his doctor has conducted have been negative.

Only half-jokingly, meanwhile, Limbaugh said he considered lying on the monthly reports he sent to WPB-based state probation officer Louis Kurtz.
Filling out the forms, Limbaugh said, was at times "surreal."

The paperwork asks for the make and license plate of a probationer's set of wheels. In Limbaugh's case, it's a 2007 Maybach 57, with an MSRP of $335,500.

Under "Your Total Money Earned Monthly," Limbaugh wrote $2.1 million on a bad month and $3 million on a better one.
