Barack Obama writes Betty White on her 90th birthday, and asks to see her long-form birth certificate:
You look so fantastic and full of energy, I can’t believe you’re 90 years old. In fact, I don’t believe it. That’s why I’m writing to ask if you will be willing to produce a copy of your long-form birth certificate. Thanks. Happy Birthday, no matter how old you are.
