According to Moonalice legend, the ancient tribal occupations of hemp farming and music produced great harmony. Such was the energy of the tribe in those times that it created hemp and music in prodigious volumes. Happiness reigned supreme in the tribe, which partied continuously for the better part of a millennium, until everyone finally ran out rope and other hemp derivatives. Hemp grew naturally throughout the land, but it didn't harvest itself. For that, hard work was required. Not much, but hard. Just a few days a year. No one was happy about having to break up the party for something as unseemly as work, but the tribal elders could see no way around it. So they created Labor Day Weekend, a three-day harvest that represented the entire work product of the tribe. You can look it up.
