Oh man, seriously showing my age here. Back in the way olden days, when telephone numbers had a word prefix, all the phone numbers were KLondike5-????, which, of course, is 555-????. The reason for this is because the 555 exchange is reserved for non-residential customers. Seems people actually call phone numbers given out on movies and TV shows, so film-makers use the 555 exchange to keep residential customers from getting crank phone calls, or calls from fourteen year old boys who think they REALLY gave out Kirsten Dunst's phone number in the movie.
That was a good post explaining about the phone number. Thanks again that was great. I bet you are right too, about people and kids trying to call the numbers. LOL Soooo funny.
