the last thing arnold wants is his kid going in BBing. The pwnings woudl be brutal. Everyone and their mother trying to defeat Arnold's kid.
Its' like when michael Jordan's kid played basketball. He was average and short. But he was on ESPN in high school. Every time, people tried to beat him to get their "i punked MJ's kid".
better arnold's kids go to college, enjoy their wealth, and just goof off. They'll outgrow this baby fat and have great lives.
