Continuity mistake: In the scene where Rube shakes hands with the animal protesters, he is not wearing the trash bag while shaking their hands. He is wearing the trash bag immediately before and after.
Continuity mistake: When Guggenheim is sitting on the bench after he dies, he reaches for the pink index card and his fingers pass through it. But then how did the index card get to the bench? He had it when the gas tank hit him, so it could make sense if he still had it "with" him, like his clothes, but if he can't touch it now, then it should have stayed with his body, inside the building.
Continuity mistake: Dolores walks to the computer and tells Georgia "Apparently Stinky5000 votes for 'Ferns and Flowers'." The first look we get at the screen shows the message "Could you tell us what the dog's name is?" and nothing else. The next two glimpses of the screen we get shows "You forgot to put detergent into the dishwasher" and nothing else. It's after the next cut that Dolores says Hungrygirl wants to know the dog's name. As Dolores walks away from the computer, we get a last look at the screen. You can see Stinky5000's message "I vote for "Ferns and Flowers'" appearing on the screen.
