I saw this in the late 1980s/early 1990s on Austrian or German television, I think in the afternoon. It could be a movie (dubbed in German) or also a German tv series.
A tough man, probably a middle-aged silent violent debt-collector type, says to someone, "If you want to catch a guy's attention, rip his ear off and hold it in front of his eyes."
Judging from the clothes, the time was present, location: in a city.
That's about all I remember about the scene. That sentence stuck in my mind and I was anxious about losing my ears for some time.
