What are some events from when you were a kid that had an enormous impact on you, that you'll never be able to forget? Can be positive or negative, or both.

My negative experience: I was at my aunt's house and her and her husband (my uncle) rented some German porn tape to watch, but it was fuking disgusting s**t, I mean really gross stuff with some old people doing absolutely appalling s**t with garden hoses. Will never forget that.

What about you?
