How often do you think First Lady Michelle Obama gets to ride shotgun?
That's not a tasteless US gun use pun - really, when do you think Michelle Obama last got to ride in the front passenger seat of a car?
As she tells James Corden - a man who genuinely can't believe what his job involves these days - it was "months ago", when she accompanied her daughter who'd just learned to drive. Before that? She hadn't been in the front seat of a car in seven and a half years.
As such, this episode of Carpool Karaoke is something of a joyous, special event as one of the most powerful women in the world talks about what she's going to miss the most from her time in the White House, her favourite tunes and secret service code names.
