Words sometimes like food can be digested with delight. In 1963 Schlitz started nationally using pop-top cans for their beer. Three years later cans were out-selling beer in bottles. Pulitzer Prize writer John Updike wrote a thirst-quenching bit for The New Yorker in 1964 about the progress of man using the beer can as a simile. This is one meaty morsel of literature to bite into.
