Matt Damon got decked out in a Santa Claus suit to help promote Water.org, a website which helps to conserve water in developing areas.
Damon taught kids about the importance of helping to solve the safe drinking water crisis.
"If you were stranded in the desert, what would you rather have: this water bottle or Justin Bieber?" he asked one child. Check out a video of Damon as Santa Claus below!
