Oh, the stories I could share... But here's my wierdest one!
As a kid, I had absolutely no idea how cartoons were made, so I had my own theory about them! Does anyone remember that Spongebob episode where Spongebob spends all his time indoors, until a green screened gorilla starts attacking Patrick and Sandy?
Bassiccly, I thought all cartoons were actors in costume in front of still backgrounds (I'd never heard of green screening yet). And how did they get these costumes, you ask?
Well, it doesn't make any sense, but apparently at the time I had no concept of creating costumes on your own, (Even though I knew my parents usually hand-crafted my Halloween costumes) so I thought the creators of these shows obtained the costumes from stores, and they were of preexisting cartoon characters that literally everyone, (Except somehow these new creators) forgot about. And they essentially stole the appearance of these characters.
What's really funny is that I had absolutely no knowledge of scaling things in movie editors. So I actually thought Plankton was played by a 6-inch tall man.
