STOCKHOLM, Sweden -- A man wanting to stay sober volunteered to serve part of his friend's one-month drunk-driving sentence. The 51-year-old Swede wanted to see if he could pose as his friend and fool the justice system, but he was discovered two weeks into the sentence. The man said, "I wanted to go to jail to stop myself from drinking for a few weeks. My pal didn't think it would work. He agreed to let me try. I borrowed his ID card and identified myself as him at the prison." He has since been charged with perjury and wrongful use of another person's identity.
