For assholes like the Fox Allstars who claim that Kerry only spent four months in Vietnam and that makes him a pussy, it should be known that while it is true he only spent four months getting shot at and saving lives and winning medals for bravery in swift boats -- he had previously done a full tour onboard the USS Gridley stationed in the Gulf of Tonkin. Swift boat duty was his second tour.
