According to Bloomberg News, back in July, Apple CEO Steve Jobs was reportedly stopped by airport security for carrying ninja throwing stars as he tried to board his private plane at Kansai International Airport near Osaka, Japan.
Confronted by airport security, Jobs reportedly said it wouldn't make sense for a person to try to hijack his own plane. He then told officials he would never visit Japan again
Maybe something was lost in translation (PUN INTENDED) and I'm not sure if I completely believe this story, but I hope it's true.
