"NCIS" agents Jethro Gibbs (Mark Harmon) and Anthony DiNozzo (Michael Weatherly) mount up and head out when a fellow agent is gunned down!It isn't exactly 'Blazing Saddles,' but DiNozzo does lend some humor to the investigation in the "South by Southwest" episode, which takes the two into the desert on horseback, accompanied by Sheriff Clay Boyd (Lance Henriksen).
And Abby (Pauley Perrette) feels responsible for the agent's death.
