Typical Govt. Mistake

I lost my mother's copy of Eliza's birth certificate so we had to order a short copy from the state to get her on our insurance. Jeremy handled this a couple of weeks ago. He finally remembered to bring it home Friday. I was looking at it and say to Jeremy- " They have her birthday wrong". They have it listed as October 17, not Nov. 17. Jeremy did not even notice. So now I have to figure out how to get that changed. How did the state even make this mistake??? It was right on the forms sent in. I thought this was kinda funny!!
