Yes. That was my reaction to the ending - he is mocking everyone who is upset by his "Puckish" behaviour. I think, he mis-spelled that, though.
I'm also a bit perturbed. Did Harlan Ellison really write that self-serving "apology"? Is this really a typical sample of his current writing style? I only ever read one collection of short stories he wrote - I still have nightmares from it, but ... I had thought from all the hoopla that he was something else.
