We were there during one of the first Star Wars weekends right after the movie came out, so I don't know if this could still happen, but:
So we - me, my parents, my sister, and my brother - were at HS, and we've already seen all the stuff they have happening for the Star Wars weekend (we were really impressed by the face characters they had available; they did a great job of behaving like their movie counterpart). We were right around where Toy Story Maniai now is, when we looked back and saw a Storm Trooper following my brother. My brother, naturally, did not find this amusing, but the rest of us did. The Storm Trooper followed him around for over ten minutes like he was wanted for something. It was great!
