It's a minor triumph for all involved that these episodes were this much fun and occasionally brilliant, and they'll likely impress fans of the book moreover than the 2005 movie did.😊
Since I never read the books, the laugh the bowl of pentunias got out of me the first time I saw the movie is because flowers are always used in slapstick comedy as a convenient item to drop on someone else's head. So having the pentunias be meta-aware of the gag seemed like a very funny idea to me.
I guess with the bowl of petunias has fallen before, possible by being knocked off by wind when they are held up around people's houses. Question is: how many times does a bowl of Petunias need to fall before normality is restored? If we know the answer to that question we would know a lot more about the nature of the universe than we do now. History repeats itself, 42 times. ;)
For people who only ever watched the movie, they will never know why the bowl of petunias thought what it thought. What's great about this, is that it works on two levels. The final pay-off is smart and just as the book originally stated the first time through, we would know a lot more about the nature of the universe once we knew why the bowl of petunias thought what it thought.
