Kenneth was known as a practical joker on-set. According to Leslie Phillips, during the filming of Carry On Constable, Kenneth (who was dressed as a policeman)went out and stopped a line of traffic, then another one - and just left them there.
Kenneth published several books before his death: Acid Drops (a wonderfully witty and sometimes downright malicious collection of assorted putdowns), Back Drops: Pages From A Private Diary (certain edited diary highlights) and his autobiography, entitled Just Williams.
He was the narrator of, and did all the character voices for, the 1980s children's cartoon series Willo The Wisp. Indeed, the blue ghost-like narrator was caricatured to look like Williams, with an elongated nose and flared nostrils.
Kenneth Williams: (quoted from his diary) It is impossible to set down the names that have given me lasting pleasure. I suppose I find myself humming Brahms (Vier Ernste Gesange) mostly, or Schumann, or Quilter, but lines I owe to a hundred sources; the delicate tenderness of De La Mare, the sheer daring in Brooke, the grandeur and serenity of Tennyson, but then, I love Henley too.
Kenneth Williams: (from the final entry in his diary, April 14 1988 Saw the News, watched the dreary saga of murder and mayhem. By 6.30, pain in the back was pulsating as its never done before... so this, plus the stomach trouble combines to torture me- oh- what's the bloody point?
