(Getty Images) (Newser) – Dustin Hoffman has joined the ranks of celebs who save lives. He was walking in London's Hyde Park when he spotted a jogger first stagger, then keel over, frothing at the mouth. He immediately called the emergency Brit number—999—and stayed as paramedics performed CPR on Sam Dempster, 27. As paramedics hoisted the revived runner into an ambulance, Hoffman told them: "Great job, guys," reports the Sun. Dempster, who's on the mend, says he has "no memory of what happened. The paramedics told me. It’s unbelievable. I want to say ‘Thank you’ to Dustin Hoffman. He saved my life."
