China Doll - S1-E3
Stupidity: Higgins tells Magnum that he needs to get out before he opens the safe. Magnum then gets all sassy and asks "Shall I open it?" and proceeds to activate the statuette that unveils it, then pauses. Higgins is outraged and then goes ahead and opens it dialing the combination. Higgins' behaviour here is absurd; he gave up and handed Magnum the victory in their petty squabble when Magnum proven nothing. Magnum is the security consultant of the house, it is unthinkable that he would not at least know where the safe is, but it's also rather obvious that he did not know the combination. You don't get a safe assuming that nobody will ever know where it is; keeping it out of sight and reach is a plus, but it's not really its point. (00:19:30)
