Student passes math, films his father’s reaction

File this endearing video of a proud papa and his son under “Warm and Fuzzy.”

Known as AriaMark on YouTube, the young lad secretly filming the video is a student in Nottingham, England, and based on his own explanation, not a very good student, at that:

A year before this video I was at a grade F in maths and you need a C (pass) to basically do anything with your life. I’ve never been amazing academically and have struggled throughout school. Neither me nor my dad nor my teachers thought I was going to get my C. I know some of you might be saying, well a C is nothing but for me it was hard to get.

Young AriaMark did, in fact, get his C and instead of just telling his dad the good news, he decided to film his reaction.

While his proud, crying father leaves the room at 2:16, the video continues filming an empty room for another 15 seconds until the young boy comes back — wearing the best grin ever.
