Someone started a conspiracy theory thread, so I'll get us back on track.
In the late 70's, I was a first year teacher in a junior high school, where most of the students were taller than me, and didn't want to take me seriously. I taught 8th grade math. When we reached the unit on prime numbers, I explained what prime numbers are, and had them memorize the prime numbers less than 100. The students informed me that my list was wrong! They insisted that 0 and 1 are prime numbers, and 2 was not. It didn't matter how many books I showed them, they simply did not believe me. When I asked them why, they said, "because Other Teacher said so." Other Teacher was a science teacher, not math. I suppose there might have been something in his curriculum about prime and composite numbers, but I don't think so.
Other Teacher was an older man who dressed like an old time gangster, in a pinstriped suit, with a cigar in his hand and a Bible in his pocket at all times. I don't think he smoked the cigar in class, but I never saw him without it. He also jumped all over another teacher who asked him what version of the Bible would be best for her to read. He whipped out his Bible, opened it to the title page, and literally screamed at her that the King James version was the only AUTHORIZED version. Then he stormed out of the teachers' lounge. I quietly told her that the KJV was authorized by King James, and I wasn't sure she needed to worry about him.
To tell you the truth, I think we all, including the principals, were a little afraid of Other Teacher. I sure wasn't about to cross him. I guess all the students he taught may still believe that 0 & 1 are prime, and 2 isn't, in spite of my best efforts.
