What was the best thing about the 1920s?

The 19th amendment to the US Constitution giving women the right to vote in 1920. Duh. That, and finger waves (which definitely would be my answer for #22, the fashion trend in history I missed out on). 

According to Professor Wikipedia, the amendment achieved the necessary 36 state legislatures to ratify the bill in August of 1920, officially making it a federal/national law, but Maryland didn’t ratify it until 1941, Virginia in 1952, Alabama in 1953, Florida and South Carolina in 1969, Georgia in 1970, Louisiana in 1971, and finally Mississippi in 1984 (64 yrs after it was enacted nationally).
