Yes, I know my chem101 teacher wasn't Heisenberg. Yes, I understand how TV is fiction. However, are you really so thick to not realize that fiction is based on reality. Fiction isn't written in a vaccum, and the most interesting plots are typically based on some real situation the author has experienced, seen/heard, etc. Yes, it is dramatized to make the really boring parts interesting so people tune in, but come on. If you don't think a Don Draper/Walter White type existed as a single person or an amalgamation of multiple people then you just have your head in the sand.

Using modern TV/Film/media in examples isn't a cluelessness on the speaker's part. It's used as something much more relatable than an esoteric story that you might or might not be able to provide a link to.
