So John had to memorize thousands of words--well over 6000. It's as if he had to recite an entire book. I don't know how he was able to do that, and I let him know that I was impressed. This was his reply:
My greatest fear is that someday thirty years from now I'll be a senile old fart sitting in the nursing home. Someone will play the song 'Here Comes Santa Claus' on the radio, I'll launch into my lines from 'A Christmas Story' and they won't be able to get me to stop until I have recited all 6,260 words. Of course, since there won't be anyone to provide the rest of the dialog, I probably won't be able to proceed unless someone feeds me my cues. I'll freeze up and go catatonic while waiting for Flick and Schwartz to say their lines.
Well, at least he survived and was able to remain funny.
