The biggest life lesson that you take away from Barney Miiller, even before the show begins, has to do with music. That bassline is just so memorable, but in a less annoying way than the CHiPs theme. Then the guitar and brass. Nice. Simple. I liked the show, even as a kid, watching reruns with my parents or Grandma and Grandpa Ost, but the shoe itself is not etched in my memory like the tune.
Life Lesson: hire a good musician to play your theme song.
