This summer my 2 year old has become Star Wars crazy.
He woke me up one morning holding his toy mini-golf club, pointed at himself and said "Luke" then started making lightsaber noises.
His official first sentence was "Artoo Wa Wa Boom." which translates as "R2-D2 fell into the water!" And extra cute, he wasn't watching ESB at the time, he was requesting to see that scene.
He dances around during the crawls, Yub Nub, Cantina Band song, and Jedi Rocks.
We tend to watch the SE because we do the Spanish language track.
I'm pleased to say he doesn't care for the PT. Once or twice I put it on, but he asks for Vader (named "Hhhhhhh-pa") or Luke.
