Merry Christmas, Christmas people! Here's a fun bit about phone numbers starting with 555, thank you Wikipedia:

555 use is restricted only in North America. In 1994, cartoonist Gary Larson's The Far Side included a panel with graffiti of a 555 number by which prank calls could be made to Satan. In Australia, 555 was at the time a standard exchange, and the Australian owner of the number became the subject of harassment, launching an unsuccessful lawsuit against Larson and his syndicate for defamation.

See, cartoonists sometimes make their mark on the world. Here's the old post!
