- Adaptation Displacement: The show was based on a series of four children's books published by Winklemania that starred an eight-year-old Shirley. Fans tend to be more familiar with the show than with the source material.
- Fan-Preferred Couple: Shirley and Bo.
- Growing the Beard: The show finds its footing in season 2, where the mysteries become more mature and complex, and a few story arcs stop popping up. Season 3 ramps this up by fleshing out Shirley and Bo's friends, making them more involved with plots and giving them more to do.
- Older Than They Think: Apparently dates to the 60-s at least. Also, there was a 1986 Soviet Comedy featuring a Distaff Counterpart to Sherlock Holmes named Shirley. That's about where the similarities end.
- What Do You Mean, It's for Kids?: Back in the day, this show was met with a lot of surprise for its plots. The show tackled a surprising amount of mature ideas, such as murders, kidnapping, cults, and human trafficking. A couple of episodes also had mentions of Nazis and Hitler.
