Studio Chalk

So umm, between classes one day I went to studio and in about ten minutes before I had to leave, I guess I was staring at the wall singing along to some musical.  The droid was already there, along with other Star Wars characters elsewhere in the room, and took some regular chalk and sketched out part of General S.S. Wicket.  His left eye got a little smeared, but you get the idea.  I found it odd how nobody seemed to notice the addition to the concrete column.  Later on, my friend Sergio decided to add a top hat, handlebar mustache, and a monocle.  He doesn't know it yet, but the Ewoks are going to retaliate for that hit on their reputation....
