Phone area codes

Springfield Telephone Area Codes are the subject of much debate in a cimpsons episode. They are to change the (Quote Homer) "Classic 636" code for 939. This causes Homer much difficulty and problems to adapt, despite "the big radio campaign, those 3 weeks in area code camp" etc. Homer even goes as far as to break away and form his own town as a result. Wehn Lenny and Carl debate the new area code they decided - "The 6 is closer to the 3 which is handy, yet the 9 has less evil connotations in the very religious world we live in".
