YMMV / Scooby-Doo, Where Are You! S1E8 "Foul Play in Funland"

• Older Than They Think: This episode marks the very first Scooby-Doo story where the antagonist is something non-human, and is not a disguise. Such elements are usually assumed to be more recent additions to the franchise.
• Unintentionally Unsympathetic: Ms. Jenkins was just thinking about the children...so she naturally reprograms the robot that had been doing its job properly to go on a rampage and attack a bunch of innocent teenagers, while she throws her brother under the bus. It's very notable that she's seen in prison in Trick or Treat Scooby-Doo!
