Mark McAllister of Global Toronto started messing up his speech during a live broadcast about Libya.  He soldiered on to the end of the report, but it became harder and harder to tell what he was saying . . . although it never became complete gibberish.The station released a statement yesterday that said he'd, quote, "suffered a minor medical issue causing him to experience a moment of disorientation.  Paramedics were immediately called to the scene . . . Mark was fully checked out and is feeling better."
