Another on that is burned forever in my mind is a public service ad that came on locally in the late 70's early 80's. I was a very young kid and can't believe I remember it at all. I used to actually play this commercial with a friend of mine. I would sit in a wagon with all my toys and he would pull me while I threw my toys out (simulating littering) and sing this song. When I ran out of toys I had I stick I would drop off the back of my wagon like my bumper fell off. The commercial had a guy in a beat up car driving down the road littering like crazy. At the end of the commercial he stopped on a hill overlooking Nashville Tn. and his bumper fell off while he kept littering. The song playing was

Tennessee trash rolling down the highway Tennessee trash
That is all I remember of the song but I remember the melody and all very well. I loved that commercial as a kid and it has burned itself deep into my memory lol.
