> I "invited" the LAPD Bomb Squad to my High School Graduation when some punk kid crawling on a roof he was not authorized to be on found a little science demonstration a friend and I had set up for the time of graduation and told a gym teacher who took the science demonstration from where it had been safely installed and placed it in his enclosed office and called the LAPD Bomb Squad (on my behalf.) "Punk kid" was crawling on a roof. He was not authorized to be on said roof. He found the OP's science demonstration that he set up on the roof to go off during graduation. The "punk kid" told a gym teacher, who contained the experiment to his office and called the LAPD. The bomb squad arrived to investigate.
