In the town where the cemetery I volunteer at is located (an historic mining town) there was once a man who owned several businesses and was quite the card. Anyway, one fourth of July he and a couple of his buddies decided it'd be funny to set off the cannon that was at the courthouse. So, they hauled it onto the main street and, not knowing anything about artillery, they just filled the tube with mining powder and put a fuse in the hole, lit it, and skedaddled (this was early in the morning). Well, luckily the gun didn't explode but it was so loud it reportedly broke windows and certainly caused quite a riot. He somehow managed not to get arrested.
So I don't doubt similar pranks happened elsewhere.
