Episode 06, "Lupin vs The Smart Safe"
Synopsis: Two brothers have invented a special safe that can only be opened by those with the lowest intelligence, which may prove to be too hard for the brilliant Lupin to break into. Lupin is disinterested at first, but is called out on loans made to his colleagues, so he decides to give it a try. Lupin believes he has the perfect technique for zoning out, but when he attempts it, things don't go as planned! Can Lupin find a way to get dumb enough to open the genius-proof safe? And why are Jigen and Fujiko holding heavy objects? It's a stupifying caper for Lupin!
