The Zodiac Killer may have noticed that "The Exorcist" movie was directed by William Friedkin, based on a novel by William Peter Blatty, and that William Shwenck Gilbert was responsible for the libretto of "The Mikado" (text of the musical work). Was this why he chose "Tit-Willow" because it contained "Will" within its text, effectively giving us "William" four times within one communication? The Zodiac Killer chose the introduction of "best saterical comidy" based upon "The Exorcist" movie winning four awards at the Golden Globe ceremony at the Beverly Hilton hotel in Beverly Hills, California on January 26th 1974, for "Best Film", "Best Director", "Best Supporting Actress" and "Best Screenplay". Therefore, it was just coincidental that the novelist William Peter Blatty and director William Friedkin had the same forename as William Shwenck Gilbert, because he featured "The Mikado" on July 26th 1970, when he gave us more verses from the stage play. This wasn't something he could have manufactured, but it was something he could have noticed, thereby inspiring him to apply a type of "spoonerism" and altering "best satirical comedy" to "best saterical comidy" in his introduction. This may have been deliberate, because this "spoonerism" gave us our fifth William.

It would have been apt for the Zodiac Killer to use a "comedic spoonerism" when writing the "best saterical comidy". It may have been one big game for the Zodiac Killer, who seemingly liked taunting his pursuers with a plethora of cryptic puzzles.
