I cannot resist a tale told to me, in fact, by a service provider, who was
at the Empiricon science fiction and fantasy convention in New York, some
years ago. At about 3 AM, six attendees decided to go to a Chinese
restaurant they knew was still open, and chose to take the subway. At the
time, this was _not_ a safe transportation route. To compound their strange
choice, they were all in costume.
As it was told to me, they were joined by four young men, wearing leather,
as is common to the Thief class in Dungeons & Dragons. Indeed, the laughing
young men pulled out daggers, or modern equivalents, and demanded purses.
At that point, things took an unusual turn. Some conventions allow no actual
weapons. Others will allow certain items, but "peace bonded" with a symbolic
seal on the scabbard. Three of the convention-goers were D&D players, and,
as things developed, things went considerably beyond "That's not a knife.
THIS is a knife."
In this case, the three drew what were, indeed, not knives.
They were swords.
After the smallest woman in the group broke one of the young gentlemens'
arms, with a firm blow from the flat of her saber, things became a bit
confused...but, soon afterwards, the four young gentlemen were spread-eagled
against a subway station wall, the waistbands of their trousers cut and
hobbling their ankles.
When the Transit Police arrived, had it explained that a sword was hardly a
concealed weapon, the young gentlemen greeted the constabulary with great
relief.
You see, the remaining three convention-goers were admirers of Star Trek,
and were suitably garbed. The young gentlemen knew only a bit about Star
Trek, but just enough, considering their recent experience with true blades,
to have absolutely no desire to determine, experimentally, if the leveled
phasers were real.
