There has got to be very little people that do not know of this classic by now. It has been airing for decades! The whistle used as the theme song has been stuck in my head from the very first time I heard it. From the whistle to all the characters in the little town of Mayberry this one is absolutely unforgetable. Mayberry has a very strong fan base to this day. I think it is because people miss the small rural town life that is very uncommon or in the past to most people today. With this classic it lives on. Long live the Andy Griffith Show!
