When you try to dial a number in area code 212 at Yahoo!, it’s really easy to end up trying to call the cops.
A number like “9 1 212…” is easily misdialed as “911…” by missing the first 2. Of course, they intercept “911” calls even though they are not fully qualified. (You’d have to dial 9911 to get the real 911, although I think they intercept that here, too.)
So it goes like this:
Jeremy dials 9 1 212 but misses the first two, notices, and hangs up to try again.
Mission Control: Mission Control, 911 was dialed from this phone.
Jeremy: Ooops, I was trying to call 9 1 212 …
They must get that a few times a day…
