Punishing your kids is a fine art -- almost as much of an art as the work these little kids did to their faces.

This father knows his two little boys did a no-no when they completely covered their faces in paint. He tries to remain serious while being the "stern dad," but can't quite pull it off. His seemingly terrified (and confused) children listen as he chastises them, while chuckling (the laughter starts around the 1:50 mark) at the same time.

Yes, kids frustrate us, but they also bring a smile to our face, even when they do something completely outrageous. And that's the joy of parenthood.
