The point is that there isn't a canonical James Nicoll tale. The point is that whenever a discussion turns to some manner in which a human being can be menaced, injured, or potentially killed, it will turn out that James has already had it happen to him. No matter how funny, unlikely, wierd (sic)), or pedestrian. He hasn't said he has a scar on his arm from being attacked by aliens with laser swords, but I would be only mildly surprised if he did. And I'd believe him.
