A Dark Knight: A Beautiful Darkness - S4-E13
Audio problem: Near the start, as Gordon tells the crook "how about you exercise your right to remain silent", the shot cuts and we can hear the audio from the different take which hasn't been spliced in properly. As a result the line actually is heard as "right to remain silent-silent."
