Joe Riquelme surprised his parents for Christmas by giving them envelope with bank documents and note saying their house had been paid off. Riquelme, a successful app developer from New York who goes by the YouTube user name joeytrombone, on Thursday shared a video showing his parents’ heartwarming reaction to his incredibly generous Christmas gift. Looking visibly nervous and struggling to keep his emotions in check, Riquelme tells his mom and dad that he has one more Christmas gift for them: a slightly dog-eared envelope folded in half. Inside, there are documents from Bank of America accompanied by a handwritten note that reads: 'Your house is paid off. Merry Xmas. - Joe.'
