I know it is to stop lunatics and whatnot from calling the phone #'s given in various movies as part of the plot, but come on already. Hollywood has to be imaginative and technical enough that by now they would come up with a series of numbers that don't include '555'. Even the cabs and buildings in movies have...555.
How many morons out there watch movies and then try to call the # in these days of 10 digit telephone #'s ? Seems to me a nut like that could just as well sit around making their own #'s up to call and do whatever it is they do that Hollywood is afraid of.
