I'm not sure if anyone bothered to pay attention to this or not, especially considering phone numbers in movies or TV are usually fake. But in Ghostbusters 2 when they show the guy outside cleaning the new GB2 sign there is a phone number posted on his little bucket truck post. I saw this the other day and was bored and noticed it wasn't your usual 555 number so I decided to call it. They weren't open at the time but never the less it was an actual company. I can't remember the name but it is some kind of neon sign company. So i don't know if anyone every knew this but it is news to me and I thought it was pretty cool, I might actually call back and see if they acknowledge doing the film or if someone working there actually did the part in the movie, well if anyone knows anything else about this please do tell.
