(CNN) - You may not have known that Thursday was International Happiness Day. Rep. John Lewis definitely knew, and he has the dance moves to prove it.
A video of the Georgia Democrat dancing to Pharrell Williams' "Happy" was posted on YouTube by one of Lewis’ staff.
“Wishing everyone a wonderful International Day of Happiness,” Lewis posted on his Facebook page and tweeted Thursday, including a link to the video.
“This is my song,” the 74-year-old civil rights icon says at one point as he dances from side to side to the chart-topper. “Nothing can bring me down.”
Lewis can be heard trying to sing along. Though he doesn't appear to know all the lyrics, he repeats the song’s title over and over with a smile on his face.
The video had over 160,000 views as of Friday morning.
“Happy” was featured in the movie "Despicable Me 2" and got Williams an Oscar nomination.
