5. Otto Bites Off His Own Tongue
Season 5, Episode 13: "J'ai Obetenu Cette"
The great Donal Logue pops up at the end of Season Five as disgraced U.S. marshal Lee Toric, the brother of the nurse Otto killed. Toric promises to force the blind prisoner to testify, but Otto defies him — by chewing his own tongue off. Whenever Kurt Sutter's character showed up, you assumed something memorably disgusting was bound to happen. This, however, still ranks as one of the grossest scenes in the frequently stomach-turning show.
