Revealing mistake: Right after the scene with the witches, Cindy disguises herself while offering coffee to the producer Corky Shimatzu. However, besides the Groucho Marx glasses and nose, she is wearing her normal outfit when a few minutes earlier, she was wearing her witch outfit, had green makeup on her face, and her hair was a completely different style. Then a few minutes later, she goes back to her play costume. That makeup must have taken at least an hour and would take just as long to remove it. Yet she changes from and back to it in a matter of minutes.

The League of Villains - S3-E16
Factual error: As the villains are approaching to Earth, South America is shown just under Asia, connected to the Arabian Peninsula and the southern tip of India. The two continents are nowhere near enough to each other to be seen at the same time from space, much less connected. They are on opposite sides of the Pacific ocean, over 10,000 miles (16,000 km) apart. (00:06:45)
