I first saw Star Wars when I was about two or three years old. Mom and dad were watching all three movies back to back, and I was sitting in a play-pen/crib-thing being bored while they watched their adult movies. I think I fell asleep between the end of Ep. V and the beginning of VI cause I remember hearing "Luke, I AM your father...," blanking out for a little while, looking up and wondering who Luke's father was, and seeing Jabba the Hutt and then going back to sleep satisfied that the big fat monster was Luke's father. Although I did wonder why he never talked in that deep voice again, just made wierd noises the rest of the time.
I think this might actually have been my first memory, and probably the most clear baby memory I have.
Yeah... my first memory was that Jabba was Luke's father. Right.
