Tony's hair changes from combed to mussed to combed several times on the boat. Additionally, Tony has a five o'clock stubble when he goes up to talk to Silvio when they're on the boat, but he's clean shaven when they're back down inside the boat again.
At the end of the episode after the dumpster is emptied, we see a guy walking toward the adult movie theater wearing boots. When he walks in the door he's wearing tennis shoes.
Tony's sister Barbara says she does not understand what Livia means when she tells Tony that she did not conspire with Uncle Junior. A bemused Barbara says she has no idea what they are talking about, showing that she was not aware of Livia and Uncle Junior's plot to have Tony killed from season one. This, however, contradicts episode fourteen "Do Not Resuscitate," the first one of the season, where Barbara tells Janice not to get involved in Tony and Livia's fight. Barbara says to Janice "Look what Ma tried to do to Tony." This leads one to believe that Barbara knew exactly what went down.
In the ending sequence there are dry dead leaves on the trees, making it look like fall. However, it's supposed to be late spring or early summer.
When Tony sees 'Spoons' in his dream, Spoons has one bullet hole in his head even though he was actually shot in the head two times.
In the overhead view of the poker game at the end of the episode, the money in the middle of table is real, but the money along the edges is obviously fake.
The overhead shot of the poker game at the end is recycled from the overhead shot of the poker game in Pax Soprana (1999) at about 4:40.
When Pussy is down on the ground you can see blood drops on his waterproof jacket.
