This is an amazing Christmas gift, and the son is so casual about giving it, you might think he's handing his parents a coupon saying he'll mow the lawn five times.  But it's so much more than that.  And the video is going viral.

The Today Show shared the video, and Youtube users have watched it thousands of times too.  The son is an app developer, and his video editing app for iPhones has become so successful, it's allowed him to pay off his parents' house and let them live mortgage-free.

They might have thought all the time their son was spending on computers back in the day was a waste, but now that he's successful, that dedication comes back to pay dividends in a huge way.  Awesome!
