Truly terrible interviewer. I can't imagine that anybody under the age of 50 could actually formulate a question that this man would care to take seriously. Plus, and this is speculation mind you, I bet the interviewer has a ridiculous mustache.
I read the article this was done for, they interviewed a bunch of over-90 entertainers (Carl Reiner, Cloris Leachman, etc) and basically just asked them what it's like to be old and still working. It was supposed to be fluff. But they must have known what Jerry Lewis is like. He's been this way for 60 years.
