17. The Christmas Day Flashback
Episode Title: "To Save Us All from Satan's Power" (Season 3, Episode 10)
The Sopranos isn't the first television show to do it and it certainly won't be the last one. But it's always rather amusing when a flashback scene is attempted and the only visual cues offered that it is indeed a flashback is a bad fashion choice here and a little more hair on a balding character's head there.
While it might not be such a stretch to imagine that Tony and the gang haven't changed much in the six years since the flashback scene in "To Save Us All from Satan's Power" originally occurred, 20-something Jackie Aprile Jr. (Jason Cerbone) playing his teenaged self looking exactly the same is rather laughable.
