NBC aired a 90th birthday celebration for Betty White on Monday, including a clip of President Obama in the Oval Office, penning a note.
It read, "Dear Betty, 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."
Obama then puts on earphones and listens to the theme from "Golden Girls."
