Before the convention itself got underway, Foolscap guest of honor Harlan Ellison was savaged by a parrot.
The story morphed somewhat throughout the event. The most marked departure from the canonical version was that Harlan Ellison had actually been raped by the parrot.
I don't hold to that account.
He didn't appear any worse for wear, although I am told that the bird's vocabulary is now studded with profanities, dark oaths, and shrieks of mortal pain.
