Not exactly a full telephone number (missing the zip code), but in 1981, Tommy Tutone released the song "867-5309/Jenny". Apparently, people in several area codes would dial this number and ask for Jenny. Many people had to change their numbers (from 867-5309) to avoid these sorts of calls. Strange, but true, one of my bosses set the Password for a login on one of our products to 8675309, I remember using the song lyrics to remind me of the password from time to time.
