Is the last part actually part of the paradox, or just a funny quip at the end. I found that bit quite hilarious, I could imagine that fitting into a Monty Python sketch or something quite well.

>The next week, the executioner knocks on the prisoner's door at noon on Wednesday — which, despite all the above, was an utter surprise to him. Everything the judge said came true.

It's part of the paradox. The prisoner believes he has proven that his execution is impossible—however, he was wrong. The paradox is how a seemingly correct argument leads to a false conclusion.
