This kid from England posted this video on youtube. This is his explanation...

"The day I passed maths. Hey there everyone the man in the video is my dad :)
I year before this video I was at a grade F in maths and in England you need a C (pass) to basically do anything with your life, ive never been amazing academically and have struggled through out school , neither me or my dad or my teachers thought I was going to get my C , I know some of you might be saying , well an c is nothing but for me it was hard to get
please enjoy the video"

Here's the video...

We still don't know if he passed English too... very unlikely... ;-)

When was the last time your kids made you cry like that?
