The camera was rolling as a son sat on the couch with his mom and dad, pulled an envelope out of his sweatshirt pocket and told them to open it.

A Christmas present "for both of you," Joseph Riquelme said in a decidedly unexcited tone as his mom began peeling back the flap.

She said with a smile that it must be "a nice present," likely knowing his intro signaled something special. What could it be? An extravagant gift certificate? Maybe a trip to an exotic locale?

But seconds after Riquelme's mom started reading the envelope's contents, her face registered shock — then she started crying.

It was a receipt from Bank of America — along with a note from Riquelme, saying that after his folks' years of raising kids and toiling with college loans, their house was now paid off.

Lots of tears and hugs followed.

Riquelme — who goes Joey Trombone on Facebook and YouTube — is the founder of Videoshop, a video-editing app for the iPhone and iPad, based in New York City.

Hours after he told friends on Facebook about the happy moment, someone shared the YouTube video link on Reddit.

He took a self-effacing route with his Facebook post regarding the occasion: "Sometimes the best gifts come in the lamest packages."

According to his Videoshop bio, Riquelme graduated from the University of California, Davis in 2006, working in the semiconductor industry for five years before trying his hand full-time in app development.
