You obviously haven't seen the unedited version. Muh'fuggin Kaiba blocks bullets with his suitcase and then promptly dives out of a window and off a cliff.
Later on, he's cornered by an armed guard. Seto Muh'fuggin Kaiba tells the man who's pointing a gun at his face that he doesn't have the balls to shoot.
