The entire show was great and multiple clips are below. USA Today reports on one of the bits:
Michelle Obama is continuing the goodbye speeches and appearances as she and her husband prepare to leave the White House next week. She wrapped her last late-night appearance Wednesday on The Tonight Show with Jimmy Fallon, with some encouragement and a few tears.
The show had supporters read farewell letters to the first lady’s official portrait, explaining what her term meant to them, before Obama appeared in real life from behind a curtain.
“Because of you, I know that my race does not define who I am or what I can accomplish,” one woman said as Obama looked on from the wings. “For years, you have shown our nation countless times, that through dignity, compassion, and respect, we can overcome any hardships.”
