My 4-yo just asked to watch Star Wars (Episode IV: A New Hope) with no prompting. So far as I know he's never seen it before, although he has seen the various paraphernalia around the house (including the movie posters for all three of the original trilogy hanging in my study).
The best part is that when the theme music started, my 19-mo old said "dar wahr," which translates as "Star Wars," how he figured that out I have no idea.
They're both sitting here transfixed watching it. They seem a bit distressed (simultaneous "uh-ohs") as R2D2 just got zapped by the Jawas.


Just the other day my three year old son asked if a tractor-trialer that passed us on the road could change into a robot! Then he said "Lets Roll!". I know I didn't teach him that, but I was quite proud, and massivly amused at the same time.
