While FLOTUS didn't tear up during her husband's farewell speech, she did have an emotional moment when Fallon surprised her by having Stevie Wonder serenade her on The Tonight Show.
In addition, the two participated in a fun segment of "Thank You Notes," and Michelle's first message to her husband ended up being the sweetest note ever.
"Thank you, Barack," Michelle said aloud as she scribbled her note as soft "Thank You Note music" played in the background. "For proving you're not a lame duck, but my very own silver fox."
Prior to the first lady's appearance on the late-night program, Fallon shared one of the most touching and emotional prank videos ever made. Unsuspecting people were asked to tape goodbye messages for Michelle, and were unaware that she was actually standing behind a curtain listening to their kind words.
