This one comes to us courtesy of hard-working Wobegoners in the Minnesota Legislature:
325E.65 SALE OF AMERICAN FLAGS.
No person in the business of offering goods at retail may sell or offer for sale in this state an American flag unless the flag was manufactured in the United States of America.
Take that, you impoverished 9-year-old Bangladeshi flag-weavers! You'll just have to find some other way to earn your $.009 per hour.
Oh, no wait you can just sell them to Twin City wholesalers. Never mind. You're good.
UPDATE: In case you wanted to put a face on this law, here it is.

That's State Rep. Dennis Rukavina, the bill's sponsor. And really, if this law were a person, I think this is about what you would expect it to look like. Am I right?
