I was watching the old Droids cartoon - the Prince and the Pirates, I believe it's called. 3PO and R2 go into a diner to get jobs. The head dude there has 4 arms and a white shirt with holes in it. With the exception of his face, this dude IS Dexter - the holes in the shirt even appear to be in the same places.
Never noticed this before. But, of course I hadn't seen the 'toon in quite a while.
