What are blue laws?

# Summary

This Stuff You Should Know episode dives deep into the surprising history and ongoing controversy of blue laws—those quirky regulations that restrict certain activities, usually on Sundays. Josh and Chuck explore how these laws originated from Christian Sabbath traditions, got enshrined in American colonial life with brutal punishments, and eventually became a battleground between religious groups wanting to preserve the day of rest and secular forces wanting unrestricted commerce. They uncover wild blue law remnants still on the books today, from Georgia's Sunday alcohol restrictions to bizarre rules about selling cars or blank videotapes, and explain why the Supreme Court has repeatedly upheld them as constitutional despite their clearly religious origins.
