From Cracked.com, 5 Lesser Known (Completely Ridiculous) American Civil Wars
It's ludicrous to imagine modern-day Iowa pulling a gun because a neighboring state disagreed about where the border should be. But the 1800s were a different time. For instance, when Missouri decided to resurvey the border with what would soon be Iowa (in a way that would, of course, make Missouri bigger) shit hit the fan.
Missouri sent in a sheriff and tax agents to collect from the settlers in "Iowa," and were met by a pitchfork-wielding mob that chased them back to Missouri. In retaliation, Missouri Governor and professional dumbass Lilburn Boggs, a trigger-happy guy who would later make it legal to kill Mormons, sent the militia to occupy the border. They were met by the, um, eclectic Iowa militia. According to one observer, they were, "...men armed with blunderbusses [basically antique shotguns], flintlocks, and quaint old ancestral swords that had probably adorned the walls for many generations. One private carried a plough coulter over his shoulder by means of a log chain, another had an old-fashioned sausage stuffer for a weapon, while a third shouldered a sheet iron sword about six feet long."
The Iowans managed to take the Missouri sheriff hostage. Meanwhile, after being beaten by what was the worst-armed cosplay convention ever, the Missouri tax agents figured they'd need to find another way to collect. So, they cut down a bunch of honey bee hives as partial payment to have something to show their bosses.

A random quote from another war:
The Michigan militia would have none of that shit, so 50 or 60 of them attacked the survey team in what would be called the Battle of Phillips Corner. Shots were fired. Nobody was killed, but they took nine of the survey team prisoner.
Now that pissed everybody off. Both sides started rapidly building up their militias in preparation for all-out civil war. Ohio raised 10,000 men. A Michigan newspaper then welcomed them to enter the Toldeo Strip and find "hospitable graves" there
Heh.
