Friday marks National Beer Day in the U.S., a day commemorating the enactment of the Cullen-Harrison Act in 1933. After 13 years of prohibition, the act allowed the sale of low-alcohol beer, and was followed later in the year by the 21st Amendment, which repealed prohibition and allowed Americans to once again legally enjoy alcohol, a beverage Homer Simpson once called "the cause of, and solution to, all of life's problems."

But it's not just Simpson who deserves credit for explaining the role of beer in society. Other Americans have spoken out about the country's most available alcoholic drink.
