The original Star Wars trilogy....
I remember bringing home each of the three movies from the local Blockbuster for the first time. I remember unwrapping the box set for Chrismas from Santa. I remember the first Star Wars toy I received; Boba Fett (a reward for being a good boy while getting teeth pulled). I definitely remember wearing out the tapes from playing them every single day after school. Heck, I can pretty much quote the entire trilogy word for word.
