Michelle Obama's 8 Best Talk Show And Music Moments After Carpool Karaoke Appearance [VIDEO]

Barack Obama just may be the coolest U.S. president of all time — as evidenced by his smooth speeches, a number of late night TV appearances and dynamite White House Correspondents Dinner comedy routines— but he might not even be the coolest person in the White House right now.

First Lady Michelle Obama appeared on "The Late Late Show with James Corden" Wednesday and took part in the latest installment of Corden's now-famous "Carpool Karaoke" sketch series. "Carpool Karaoke," which involves Corden driving stars around while they sing popular songs together, is his most popular bit and the First Lady was more than game to join in for a few tunes.

Michelle Obama appeared on "The Late Late Show" to promote her new Let Girls Learn initiative, which aims to raise money and awareness for the 62 million girls around the world who do not have access to education. Corden, the First Lady and later rapper Missy Elliot joined forces on songs from Stevie Wonder, Beyoncé, and even an original song written for the Let Girls Learn campaign.

Michelle Obama is no stranger to late night TV appearances or fun musical moments. Here are 8 more times she impressed us with her humor and her harmonies:

1. Evolution of Mom Dancing

One of her biggest efforts as First Lady has been her "Let's Move!" campaign to tackle childhood obesity by promoting exercise and healthy eating. To promote the initiative, Obama joined "Tonight Show" host Jimmy Fallon in 2013 to step and clap their way through the "Evolution of Mom Dancing," mocking the awkward and spastic moves moms throw out on the dance floor. The sketch continues to be one of Fallon's most popular of all time, even inspiring a reprisal last year.

2. Let's Move Fitness Challenge

Before Fallon was the host of "Tonight Show" — and before the "Evolution of Mom Dancing" — Fallon and Michelle Obama teamed up to promote the "Let's Move!" campaign in by staging a fitness challenge between the pair in the White House. The sketched aired on "Late Night with Jimmy Fallon" in 2012 and featured a cameo from Bo, the Obamas' dog.

3. Michelle Obama Jumps Rope

Again promoting the "Let's Move!" campaign, Obama showed up at "Live with Kelly" and surprised a group of young kids from the Team USA High Jump team for some double dutch jump roping. After Kelly Ripa, the show's host, stumbled in her attempt between the ropes, Obama stepped in and made it look easy.

4. Turnip for What!

While taking some questions on Vine in 2014, someone asked Michelle Obama a question referencing the DJ Snake and Lil Jon song, "Turn Down for What." Obama responded by pulling out a turnip and parodied the song with the line, "Turnip for what!" Leave it to the First Lady to promote eating vegetables and still make it cool.

5. Michelle Obama Breaks It Down

Last year the First Lady visited "The Ellen Show" to promote her "Give Me Five" campaign to encourage kids to exercise. Host Ellen DeGeneres, famous for her love of dancing, challenged the First Lady to a dance-off. The rest is history.

6. iCarly

In 2012, Michelle Obama appeared on the Nickelodeon comedy "iCarly" to show support for America's military families. She got the chance to show off her acting skills and her dance moves, while also connecting with the kids.

7. Michelle Obama Dunks On LeBron

President Obama is supposed to be the basketball player, but it was his wife who got to dunk on NBA star LeBron James while recording a promo for the "Let's Move!" campaign in 2014 with members of the Miami Heat.

8. Ew!

Every time Michelle Obama and Fallon get together on "The Tonight Show" it is must-see TV. While the pair's dancing sketches are their best known collaborations, the First Lady once showed off her improv skills during one of Fallon's popular "Ew!" sketches. She teaches Sara and Stacy, played by Fallon and Will Ferrell, how to eat healthy.
