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!
Cue the awkward dad dance moves!
Seriously, we hope Matt's daughters weren't watching! But at least it was all for a good cause!
Ch-ch-check out the hilarious clip (below)!
