When our office moved, the phone book listed our office number as Kansas, State of.
I can't even remember the variety of people that would call our office thinking that number would connect you to whomever knew the answer. Taxes, drivers licenses, SRS.... the list is endless.
We also must have gotten a number that some dead-beat had in the past. We get a couple calls a month from collectors. I've started to tell them that they will have to sue me to get any money out of me.
Occasionally we do get a telemarketer, typically from a phone company. It's fun to tell them that you would love to sign up, but they will have to get approval from the boss first. Then give them the governor's number.
