Watch Michelle Obama Command Catchphrase on 'Fallon'

Jerry Seinfeld, Dave Chappelle team up against FLOTUS

Michelle Obama and Jimmy Fallon teamed up against Jerry Seinfeld and Dave Chappelle for a wild three rounds of "Catchphrase" on 'The Tonight Show.'

Michelle Obama, Jerry Seinfeld and Dave Chappelle joined Jimmy Fallon for a rapid-fire round of Catchphrase on The Tonight Show Wednesday.

Fallon and the First Lady teamed up against Chappelle and Seinfeld – who came ready to play in a tuxedo – for three rounds that descended into chaos. Among the early highlights were Obama doing the robot and Fallon saying "Your husband wore these on the pitcher's mound" for "Dad Jeans." FLOTUS immediately answered, "The mom jeans?"

The game grew even nuttier and more competitive in the second round as Fallon hesitated too long for Obama's liking with his Beyoncé impression and Chappelle started breaking the number one rule of not using a word in the answer as a clue. Seinfeld jokingly accused Fallon of losing control of his show. Chappelle quipped, "Yeah don't lose your show."
