Human beings are pretty much organic tape machines. We hear something and then play it back over and over again. Unlike a tape or CD we tend to garble the play back so, after main iterations the message is almost unitelligable. Such as this:
Original message: John's Dog has flees
Repitition: This guy I knows dog has flees
Repitiion2: That guys freinds dog has flees on its nose.
Repitition3: You know that reminds me, Johns got some flee bights on his nose too.
Repitition4: Flees tend to hang out on the noses of dogs and people. They like it (poor content being embelished with made up information)
Repitition 999: Today Congress has enacted landmark legislation banning certain types of chemicals thought to bring flee born viruses to the nasal cavity.
I listen to people talking to each other at work and I can tell if they are getting their info form a tv show. Most people try to pass off this info as some deep college induced knowledge that they had to struggled to attain. They spout off about all sort of shit. Experts on the Cuban missle crisis and Jazz abound. Funning thing is that the experts usually change their area of expertise just about a week after the latest round of PBS or Hitler Channel documentaries. If I bring up some other topic that hasn't been on tv inthe past week people get that 1000 yard stare and search their tv memory banks for info they don't have. If your going to talk about something you've seen on tv then just say so. Instead of trying to co-opt Ken Burns.
