Jack Bauer probably could have lettered in three sports in college if he wasn't busy becoming Jack Bauer.  Point being, the man is an athletic freak.  This kill comes from episode 22 of this year, and it features an incredible full speed baseball slide.  Jack sprints from one side of a warehouse to the other, slides feet first, and takes out one of Cheng's henchman with one shot while sliding.  Incredible work from Jack.
