First time I ever heard of the guy was when I was in middle school. I can't remember the reason, but my class and I were shown an old 90's animated version of his "Soul Music" story. I found it interesting, but didn't realise until later that it was based on a book. My parents got me that book for Christmas the same year and I instantly loved it. Afterwards, I just couldn't get enough of the guy's Discworld novels, and I still read all of them today, with "Wyrd Sisters" being my all-time favourite.
