I remember and just saw again that movie with Ed Norton and Robert Dinero about robbing the kings scepter that was priceless, Norton pretended to be slow and partially disabled in the head adoring everyone at the French Commerce facility to give him a job and feel sorry for him all the while he was pretending and at the same time sizing up the facility, the plans, the structure so Robert dinero could Robb the place with Norton providing everything needed under the noses of all the guards and staff of this fortress, in the end he was found out and outed and got umgatz because Dinero smelled a RAT, Dinero got the prize and Norton looked like a bigger idiot then he played because in the end you always get found out and he tried to pull a fast on on everyone, hahahaha that’s what came to mind with this guy Orlando John!
