Grape Nehi Soda - Favorite drink of Corporal Walter "Radar" O'Reilly, the naive company clerk on the military sitcom M*A*S*H/CBS/1972-83. When he visited the officer's lounge or Rosie's bar, Grape Nehi was his beverage of choice. Grape soda was also the favorite drink of Atlanta-based lawyer, Ben Matlock (Andy Griffith) who enjoyed "washing down" a hot dog snack with a cool, bubbly bottle of grape soda on episodes of the legal drama MATLOCK/NBC/ABC/1986-95
