I figured he was more of a TAB guy the original sugar free cola!
Tab (stylized as TaB) is a diet cola soft drink created and produced by The Coca-Cola Company, introduced in 1963. Coca-Cola's first diet drink,[2] Tab was notably popular throughout the 1960s and 1970s. Further, several variations were made, including a number of fruit-flavored, root beer, and ginger ale versions. Caffeine-free and clear variations were released in the late 1980s and early 1990s.
