Continuity mistake: In the scene with the multiple versions of Stewie and Brian come back to 1999, one Peter is with one of them. When Stewie asks everyone to vote between 9/11, Peter is standing in the foreground, but disappears when one of the Stewies says Brian had his throat slit. (00:18:25)
Continuity mistake: When Peter (from 1999) arrives at Quagmire's house for the stag party, the window is small. But in the next shot when Brian looks through the window, it is a lot bigger. (00:05:55)
