And since it's probably still unclear, Scooby Doo is relevant because of the oft-mentioned phrase "You meddling kids!"

It's actually NOT the best example of the word "meddling" in this context. "Do not meddle" usually refers to powerful forces that will destroy you if you mess up, whereas Scooby and Co. are just meddling with con-artists, and they usually LEARN stuff by meddling in the first place. But I couldn't think of a better reference offhand. Did a search for "Meddle with forces" and similar things and couldn't find a source that seemed suitably ancient that it would been the original line or anything.
