What was "normal" when you were a kid, that is taboo/banned/shunned/shocking nowadays?

When I was a kid, it was common for friends at 6 years old, walk to the store to buy cigarettes for their parents. When I was in High School, a few teachers (mostly coaches) banged students, we had a smoking area for students, and we had "Slave Day" where students would put themselves up for auction to be a slave for a day to another student or faculty member. One black student was bought by a teacher, and had to put her clothes on backwards, and wear a sign that read, "I love my master!"

What are some of yours?
