Usually, it's annoying to hear two radio stations at the same time. Once, during the '80s, however, interference between two stations amused me. While one AM station aired a furniture store commercial, another station's music gave the commercial unintended syrupy underscoring. As an announcer raved about the incredible furniture bargains, a crooner on another station sang, "It's truuuuuuuue...It's truuuuuuuue..."
It would have been even funnier if the commercial had touted lounge furniture.
