This thread goes back a ways, so I can't say if this has been raised before or not, but when they use 555 in phone #'s in movies or tv shows. Especially dramas/thrillers that are supposed to be more serious, it totally blows my suspension of disbelief for the moment. Happens on "24" all the time.

I know they supposedly have to do that so the 'tards that see a real # won't go, "huh huh, I'm gonna call that #...it'll be funny." But here's an idea (insert lightbulb smiley here)...set up a real # that answers with some lame recorded commercial. They might even make money by selling the "spots" for the right of sponsors' #'s getting used in their show.
