I once caused my High School to be evacuated. Dead coyote placed under a trash barrel next to the air conditioning intake causes unpleasant fumes.
AND, I once made a remark in a HS chemistry class which the self-proclaimed school genius took seriously. He blew up the lab and we both had to write a 5,000 word essay of fire prevention.
Those were the days.
Hell, I made a thermite flare and got the teacher to light it in the sink. Burned clean through the porcelain crucible and burned a hole in the granite. It was great.
