Continuity mistake: When Paulie Walnuts is talking to Tony in the hospital room, the close up of the heart monitor shows the heart rate in highlighted text, with the word "Tachycardia" flashing. In the shot from Paulie's point of view, the heart rate is in normal text and "Tachycardia" is not flashing.
Cold Stones - S6-E11
Deliberate mistake: Tony smashes AJ's front windshield of his Nissan SUV one time with a plastic sports helmet and it leaves a hole 4 times the size. Not only is the scale size of helmet to hole incorrect, but front vehicle windshields don't shatter like that. Modern windshields are made of laminated safety glass, which consists of two curved sheets of glass with a plastic layer laminated between them for safety, and bonded into the window frame. It would've taken many impacts to cause such a hole, not one hit. (00:49:00 - 00:49:45)
Other mistake: In season 5 episode 7, Tony is talking about JFK, and said he was in grammar school when it happened. However, in this episode Tony celebrates his 47th birthday. He was probably born in 1960, so he would have been no more than 3 years old and not in grammar school when JFK was president. (00:26:36 - 00:38:02)
The Fleshy Part of the Thigh - S6-E4
Continuity mistake: The card with the proverb stuck on the billboard keeps swapping positions depending if the angle is medium or close.
Revealing mistake: The Ukranian woman's body by the stairs keeps changing positions all the time (depending on the angle), despite her being dead.
Visible crew/equipment: While Tony and Paulie are alone aboard the rented boat, Tony questions Paulie about being the joke leak. When Paulie denies it and says, "It wasn't me, Ton'... That's right," Tony lifts his beer and drinks. It then cuts to a wide shot of the swaying boat, and at the top of the screen, we see a hand move atop the steering wheel at the helm; we even see the top of the hair of this crouching crew member as the wind blows, right before this shot cuts away.
Visible crew/equipment: During one of Tony's coma dreams, when the hotel elevator is out of order, Tony uses the stairway and then ends up falling down a flight of stairs. Just before he lands, we can see a crew member's hands holding a camera steady (filming the stunt double's close-up view) at the bottom left corner of the screen.

Visible crew/equipment: When Tony and Carmela are in their kitchen, Tony looks in the fridge and cabinet. Then, just as Tony takes a seat at the table, an actor's T-mark becomes visible on the floor in front of the fridge, behind Tony.
Continuity mistake: At the Miami restaurant, when Tony, Paulie, and Beansie lift their champagne flutes for a toast, in the close-up Beansie holds out his glass with his right hand, but in the two wide shots he holds the glass out in his left hand.
Visible crew/equipment: At the hotel's complimentary breakfast buffet, Paulie loads up a plate filled with Danish and Yoplait for the drive down to Florida. It then cuts to the Wycoff Therapeutic Center, and at the start of this first shot, we can see the boom operator (papers in the back pocket) with left arm up, at the right side of the screen. The reflection of the moving boom pole is also visible over the fireplace mantle.
Continuity mistake: Paulie serves Tony a plate of rigatoni with a big slice of bread. After a few bits of rigatoni the bread disappears from the plate. (00:49:05)
Continuity mistake: Tony moves his wine glass and pours some wine. He places the wine bottle down in front to his left side. In the next frame the wine bottle is now to his right. (00:54:06)

Answer: That's not Jimmy, just a look-a-like. Jimmy's short and stout, the guy in "Christopher" episode is tall and medium built. The hair is also different.
