>>99653312It was just a thing for remembering area codes, mostly for when you're telling people from out of state your phone number
It's kinda hard to explain to people nowadays. All it really was was that a mnemonic is easier to remember than a number
It was something people stopped doing in like the 70's though. The only reason they did it in the Simpsons was because they used the "555" area code, which is the fake area code that all fictional phone numbers have, and I guess they felt saying "555" made it feel less real somehow
