with the president and first lady, give us a little bit of a history lesson, because it's got to be a pretty unique club, somebody who has hung out with 13 american presidents. >> exactly. can you imagine, a, being old enough to have met 13 presidents? i think it was back in 1951 when she was a princess before she was the queen that she met her first president. she's met 13 out of the 14 that there have been. it's just linden johnson who she never met, and that meeting she was deputyized by her sister, princess margaret, who did meet linden johnson and that was dramatized in "the crown" and it was alleged that princess margaret got into some sort of drinking contest and was reciting rude limericks with the president and i don't think that will be going on tomorrow at windsor castle between the queen and president biden. >> what will be going on?
