Roughly forty Ozzy Osbourne fans invited to a pre-party before the Ozzy/Rob Zombie concert in Fargo, North Dakota, were greeted with an unexpected surprise: Handcuffs! In what has to be the best sting operation since To Catch a Predator, invitations were sent out to people who ignored court summons, didn't pay child support, failed to pay fines, etc. Approximately forty Ozzy fans (or Rob Zombie fans, to be fair) responded to the invite and attended the bash, which was held at the concert venue by PDL Productions. Little did they know, PDL stood for "Paul D. Laney," a county sheriff, and that all those meaty guys wearing PDL T-shirts were actually deputy sheriffs, probation officers and local DEA members. Rather than boozing, the miscreants who showed up got arrested on outstanding warrants. "It was more of a warrant party," Laney joked. Some on the cuffed end even thought the elaborate ruse was funny, but a few turned hostile when the reveal was made. We're really hoping this whole affair was taped. It's got Dateline written all over it. So be warned, the next time the Blizzard of Ozz blows into your town, do not attend the pregame festivities if you're hiding from the law.
