A New York app developer gave his parents a Christmas to remember when he surprised them with news that he had paid off their mortgage.

Joe Riquelme posted a video on YouTube of himself and his parents, taken on Christmas Day, when they opened an envelope that contained a hand-written note saying, "Your house is paid off, Merry Xmas — Joe."

By Saturday morning, the video had more than 1.7 million views.

Watch as Riquelme, creator of the video-editing app Videoshop, passes the envelope to his mother to read.
