Watch: Popovich wipes sweat off Patty Mills' face during interview

Gregg Popovich can come across as a grump at times, but the San Antonio Spurs head coach does have a comical side.

Point guard Patty Mills was speaking to reporters Thursday when Popovich came up beside him and began wiping sweat off his face.

Earlier in the day, Popovich and Mills stopped by a local elementary school to give out 200 pairs of shoes to students on behalf of Shoes That Fit, a nonprofit organization that provides shoes to children in need.
