The murders of Nicole Brown and Ron Goldman didn't take place inside Nicole's house.
Also, Nicole didn't keep the name of Simpson after her divorce so she wouldn't have has the name Simpson on her mailbox.

The area rug & TV both vanish when Anna drops her soda.

The TV could be explained away by it simply being just outside the camera's view but the rug should still be in frame since it's directly at their feet.

When Peter walks into Chris' room he walks directly to his bed.



When he discovers the dead frog he walks to a window to throw it out, however he simply backtracks the same path he came in the room but there's a window where Chris' door was moments earlier.

It could be explained away by the possibility Peter simply walked to a different wall that has a window but as evidenced by the background, Peter is never out of sight of the computer desk.



Even if we are supposed to believe he's at a different wall, it still doesn't explain the sudden appearance of the dart board that's not on the wall to the right of Chris' computer when Peter walks in but appears as Peter approaches the window.

The ticket Chris throws on the ground has vanished when Anna runs away crying.

Incidentally, the other people in line and the ticket taker have vanished as well when we see the far shot but that could be explained away as, while Chris and Anna were fighting the line continued and the box office closed, despite the fact we never saw them move and Chris & Anna were standing in front of the window the whole time.

Chris has cleaned up half the spot but when Peter enters and gives Chris bad dating advice, the spot is whole again.

Also the rag has apparently vanished as well.

Madonna

When Chris sees Anna, he fantasizes about serenading her with Madonna's 1985 song 'Crazy For You'. It is included in the film and soundtrack to the 1985 motion picture 'Vision Quest'.

Stewie: "God, this is a more disturbing sight than Tom Hanks and E.T. in Philadelphia"

E.T. the Extra Terrestrial attempts to cure Tom Hanks' character Andrew Beckett in an alternate version of 1993's 'Philadelphia'

Mort: "Ahhh... Krystallnacht!"

Krystallnacht aka “Night of Broken Glass” took place in Nazi Germany November 7, 1938, it saw the destruction of more than a thousand Synagogues, the ransacking of tens of thousands of homes, and more than 30,000 Jewish men taken away to concentration camps.

Wilhelm Scream

When Peter's pirate crew blasts the telephone pole the famous Wilhelm Scream is used as the man falls.

Peter: "I've screwed up more than Disney did when they cast Michael J Fox in that Zorro remake"

Seeing the illegible scrawl on the wall is a reference to the fact Michael J Fox suffers from Parkinson's Disease and obviously couldn't make Zorro's trademark 'Z'

Lois: "You're not the first person whose life he screwed up"

Peter was (apparently) responsible for the 1994 murders of Nicole Brown and Ron Goldman

Men At Work

Peter provides backgorund music for Chris' date by attempting to sing the 1981 Men At Work song 'Down Under'
