As Al points out in the first message in this thread, Google offers this tollfree number so you can make calls to business numbers for free, on Google's dime--you call 800-446-4411, and when it answers, you tell it the name of the business you want to reach (there are a lot of options, like just asking for a type of business, like pizza delivery), and it dials the number for you. It's explained at
www.google.com/goog411. You can look at it as either another way to make us feel warm and fuzzy about Google, paving their way to take over the planet, or as a genuinely useful (but abusable) thing. I don't know if it can be tricked into connecting to any number, not just businesses.
The unfortunate part is that the company or person who receives the call will see it displayed on their caller ID, just as that very number (800-446-4411), so the service also allows callers to mask what number they're calling from. As Al says, "Wait until sleaze marketing gets a whiff of this number." And as RB found, sleaze in general has already gotten a whiff of this number's cloaking possibilities. And to piercingvision, who says "Customers don't call from 800 numbers"--well, they did now.
Al's story about someone wanting to sew wire into his jacket to stay warm, is interesting. Maybe he was going to wire it up to a power source and have an electric blanket jacket? If there was no power source planned, THAT's what would have made it weird.
