Stupid Criminals seem to always leave some glaring piece of evidence behind.
But give today's Stupid Criminal credit, he did try to get rid of the evidence.
18-year-old David Zurfluh of Alberta, Canada, was stopped on suspicion of driving under the influence.
While sitting in the back of the patrol car, police say Zurfluh ripped the crotch out of his underwear and stuffed the fabric in his mouth.
When confronted, Zurfluh told the Royal Mounted Police he hoped the cotton fabric would absorb the alcohol.
He took a Breathalyzer and it did not work. Zurfluh blew a point .09 when given the Breathalyzer, but the testimony did break up the courtroom.
