There was a smaller thread several years before that one too:

A lot of these were recorded local to my childhood home. The gentleman doing thr voice work also did work for a local radio station. His voice was very faniliar as a result. The voice of the K-Mart guy being on the radio seemed perfectly normal to me. Now I know that's just an artifact of where I grew up.
