Puddle of Mudd frontman Wes Scantlin had a bad weekend in Minnesota.

First, he gave a half-assed (and seemingly lip-synched) performance at Halfway Jam on Friday evening. Then he got arrested Sunday morning.

The charges? Refusing a DWI test and fleeing police...at 100 MPH. A preliminary breathalyzer test put his BAC at .310.

Minnesota's legal limit is .08.
