First time I ever got cable tv as a kid back around ‘82, WGN-Chicago was one of the stations they carried (back when there were only about 20 stations or so on the dial), and there were always those ever-present Empire Carpet ads. I saw them so often I couldn’t forget their phone number if I tried... “5-8-8 2-3-Hundred - Em-PIRE !”
I could have written the exact same post as you. Another phone number I’ll never forget, for the same reason, was that of Empire’s competitor, Lincoln Carpeting: N-A-2-9000. (”When you’re thinking...Lincoln Lincoln...better carpeting for less...call National Two Nine Thousand, National Two Nine (riiiing!) Thousand.”)
