I'm pretty sure that all little kid's heads are enourmous in comparrison to their bodies. That's the one of the only two things I remember from my child development classes
I dunno, but that storm trooper costume seems cruel to me.
On that note someone needs to explain to me the appeal of dressing up like a storm trooper. It's like someone into basketball dressing up as a member of the Washington Generals. Why not rebel alliance troops or members of Rouge Squadron?
There were some cool Storm Troopers, but they were mostly just cannon fodder. I just started reading a Star Wars novel, Allegiance, and it is based around some bad ass troopers who are on the lamb from the Empire. They go around kicking some ass and Mara Jade is also in there somewhere.
