Matt Damon is good at SO MANY things, but apparently dancing is NOT one of them!
The 44-year-old star of The Martian recently made an appearance on Ellen where he talked a bit about water.org, a charity that provides clean and safe water to those in need!

Well, Ellen DeGeneres, generous host that she is, offered to make a $20,000 donation! But ONLY if Matty was willing to whip and nae nae for it!
