"Aren't you a little short for a stormtrooper?" - Princess Leia

Or Darth Vader, or Boba Fett, or an Imperial officer as this photo can attest.

Check out the Tusken Raiders in the back. (Go Raiders! Woooo!)

PS - I will admit to a wee bit of Stormtrooper costume envy. Just a little, though. My unhealthy interest in Stormtroopers, as was pointed out by ETS, isn't that unhealthy.

Yet.
