Episode Title: "Chasing It" (Season 6, Episode 16)
You would think the producers would have more important things to show than Tony battling a mean case of diarrhea or Adriana vomiting all over an FBI agent. But you'd be wrong. While the show's occasional fascination with bodily functions served a psychosomatic purpose in some instances, in others it was just downright gratuitous. And gross.
Case in point: five episodes after we've last seen—or really even thought about—Vito Spatafore, whose homosexuality was revealed the previous season, there's a fairly inexplicable one-minute scene in which Vito's son, Vito Jr., reacts to his classmates' bullying by shitting in the shower... then stepping in it.
