All right this movie has the Joker middle aged and Bruce Wayne a toddler. Some viewers said isn't it weird that the Joker will do criminal battle like 30 years later with Batman. In fiction all is possible. But, is this even supposed to be the very same Joker that later battles Batman? I think this Joker the prototype for a different individual who (in the same clown look) in 30 years will do battle with Batman? It almost always all happens in just one city (Gotham City). Few viewers imagined the latter.

Now to the rest of the analogy. In eigth season episode of LHOTP a man stops by. He looks like Col. Harlan Sanders and the man wants to start a restaurant where they serve only fried chicken. Viewers usually automatically presumed this was supposed to be Col. Sanders. But was it really? The show is set in what year-1889? Wasn't Sanders barely even alive yet at that time? How is he a grown man in that year? A few viewers slightly better thought maybe this was supposed to be his father. He looks almost past the age of having son. How about grandfather? Great-uncle? Best yet to come. Probably just about no viewers thought that this man was no relation to Col. Sanders. But that he started a very small chain of chicken restaurants in the south in the 1890's and the chain existed until the 1930's. And Sanders ate at the chain, saw the picture of the guy-founder on the wall and modeled himself after him. That is the best interpretation. And one similar to the Joker one above.

Viewers show little imagination in general. One episode of the sitcom "Good Times' had JJ Evans character having a strange dream. This ep was put on Youtube and a viewer said this show was so realistic till this far-fetched ep. Someone else replied something like: "What is far-fetched about it he is just dreaming". Thus, it is not really happening to JJ's character. More imagination when you view please!
