I saw a scary-looking documentary about the cult on TV when I was a kid. My mother didn't wait to warn me not to come into contact with "people like that".

I don't remember anything about it except for the interesting-sounding name and a vague image of its Japanese leader. The closest I've gotten to cultists was Jehovah's Witnesses knocking on my door, asking what I thought was the problem with the youngsters of this generation.
