 CONT: When Bob and Doug are pulled up to the signs showing them  which direction to go (The Insane Asylum, the Castle, the Brewery,  etc) the first shot of them sitting in the cab show the dice hanging  from their mirror have the sides showing the two dots. After a quick  view of the signs we are shown the boys in the cab again but this  time the dice have changed and we see the sides showing four dots on  each one.
