when growing up, I always get my butt whipped from my parents when I do something wrong. It thought me not to do that again. People these days is to damn soft and allowing kids to grow up to be disrespectful and dumb.

But in this case with the kids education, maybe he needs to study more and spend less time on video games? I don't know the actual issue leading up to his bad grades, but that punishment is well learnt and wont be repeated again I bet.

I don't hold it against my dad for whipping me often when I was a kid. I don't think it was a good way to teach me a lesson but it's fine, whatever.

However, to take a video and post it online and think this is a good measure to take to teach your children a lesson? WTF. Utterly retarded. And for what? Bad grades? That's a retarded parent. 

If you think good grades are the sole reason you will get anywhere in life or if you fail school then you get no chances somewhere else, well.... you are retarded too. I am in my late twenties and I am where I am not because I just get good grades.

Self-esteem issues, which these kids will probably be plagued with, can be the biggest thing to stand in the way of hard-work and talent. Without high-self esteem, success is impossible. Without good grades? you can still pave your way through life and succeed.

Damn this dad is a savage, definitely not the best way to punish a kid

This is what happens when society says you can't spank your kids.

These kids just need to save up 10-15 dollars for some clippers.  I bought clippers for 15 dollars more than a decade ago and I have only paid for 1 haircut in about 20 years.

For the brilliant minds thinking this is ok, you obviously went to amazing schools. I totally see the manifested benefits of getting good grades in the way you think.

This will probably do more harm them good. Not that long ago there was a girl that committed suicide shortly after her father cut off her hair she had other problems but her father cutting of her hair surely didn't help.

The kids should tie the father down and tattoo 'Give me a hard time' across his forehead.

Its kids if you watch the entire video you will see that he gave messed up haircuts to both of his sons.

Yeah, the first time I missed when he panned and I thought he was the same one punished with different ridiculous haircuts in different moments of his life (although I thought the second was resembling the first, but curiously he didn't look like he was the same kid, and actually he wasn't).
Watching better, the second, although calm, looks moderately pissed off, while the first has a worrying blank expression.
