Easter eggs

Mr. Korman,

After devouring your early books during my own childhood, I’m now having a blast reading them with my 9-year-old son. 

We just finished  Lights, Camera, Disaster! and he and I both noticed that in addition to some plot similarities between Jordie Jones’ movie plot and Who is Bugs Potter?, the release party took place at the same Toronto hotel. We were delighted that these stories appear to be in the same Korman Cinematic Universe. 

Is there any other crossover between those two series that we should look for in other books?

Thanks for years of entertainment that truly crosses the generations.
