"I was taking sleeping pills and liquor and I went on and I could not remember a line. You know what a terrible feeling it is not be able to remember your lines?

Video: Sid Caesar guest-stars on the season four opener of The Hollywood Palace (in color) on September 17, 1966 (from the Internet Archive). Look for the sketch he does with Joyce Jameson at 32:44, which Variety said "...had the air of exaggerated truth. It had funny moments and excellent execution."
Sid Caesar is an Academy of Television Arts & Sciences Hall of Fame inductee.
