Actor Jeffrey Jones, the grating high school principal from 'Ferris Bueller's Day Off,' pleaded no contest in July 2003 to a felony charge of paying a 14-year-old boy to pose for explicit photos. Jones was sentenced by a Los Angeles judge to five years probation and ordered to register as a sex offender and undergo counseling. Jones, 57, posed for the above Sarasota, Florida arrest card photo in December 2003 because he's required to check in with local cops when he leaves L.A. for more than a few days.
