Deleted Scene from Volume 9:

(As Peter storms out of Angela's house)
Peter: Fine fire me! I'm through being harassed by you!

Oh and by the way, they're real & they're spectacular.

Error in Continuity: When Stewie's play opens the Griffins are sitting in the front row but when Peter pulls out the video camera they're suddenly sitting in (what appears to be) the third row.

Error in Character Behavior: In this episode Stewie suffers from severe stage fright but in the episode “From Method to Madness” he performs many times on stage with no problems what-so-ever

Error in Continuity: When the “Save Terri” groups sings “Oh-oh-oh Terri Schiavo, she's kind of alive-oh”, the clock above them shows 5pm but when Stewie rushes on stage the clock shows 4pm.

Error in Animation: In Angela's fantasy, when the dolphin carrying Peter is leaping in and out of the water there is no reflection of the dolphin or Peter.

Granted this is a fantasy but when the cliff in the background is reflected in the water, even animated logic suggests everything should be reflected.

Error in Continuity: When Peter is drowning his sorrows, The Drunken Clam is full of people.
The booth behind Peter is empty but there's a couple in the booth to the left (as the camera sees it) of the one directly behind Peter.

When Horace makes a crack about bringing Peter's lady boss in to straighten him out, the bar laughs but when Horace tells Peter he's just kidding the booth the couple was in is empty.

In this episode's only deleted scene from Volume 9, as Peter storms out of Angela's house, Peter says the line “Oh and by the way, they're real & they're spectacular”

This line was spoken by Teri Hatcher's (1964-) character, ‘Sidra’, in the episode of the NBC sitcom ‘Seinfeld’ (1989-1998) titled ‘The Implant’. In the episode the discussion was wether or not Sidra had breast implants or not.

Stewie performs in the pre-school play “Terri Schiavo: The Musical”

Terri Schiavo (1963-2005) was a Florida woman who suffered massive brain damage due to lack of oxygen after suffering from cardiac arrest and fell into a coma. After two years she was diagnosed as being a persistent vegetative state. When her husband, Michael, petitioned the court to remove her from her feeding tubes this sparked a debate with her parents, which in turn lead to 4 years of court cases and even Congressional debates on the right to life and living wills.
Michael ultimately won the right to let Terri finally rest and her feeding tube was removed and she died on March 31, 2005.

The character Jared who talks to Stewie about the role of the ‘Plug’ is a nod to the 1993 movie, ‘Dazed and Confused’ & the character ‘David Wooderson’ played by ‘Matthew McConaughey’, which explains the use of Seth Green's McConaughey impression.

In the film David although having graduated still hangs out with high school students.

American actor Richard Dreyfuss (1947-) appears in this episode watching the pre-school play.

While filming him, Peter makes allusions to his film, ‘Close Encounters of the Third Kind’ (1977).
He then quotes a line from ‘Jaws’ (1975), “I think you're going to need a bigger boat”.

Peter watches the celebrity gossip show ‘TMZ’, complete with host Harvey Levin (voicing himself) and correspondent, Max Hodges (blond guy).

During the broadcast, American actress Rene Russo is mentioned.

Peter: From now on I'm going to be right where the action is, like my uncle, the guy in the white hat Griffin

Peter's latest fictitious relative is actually James R. Leavelle, the man who escorted the killer of President Kennedy, Lee Harvey Oswald, through the basement of Dallas Police headquarters.
The photo shows the moment Oswald was shot by Jack Ruby.

(DVD Only) Peter rushes Rubik, the Amazing Cube as he comes out of a club.

‘Rubik, the Amazing Cube’ was a short lived children's cartoon that lasted 12 episodes from 1983-1984 that attempted to cash in on the Rubik’s Cube craze of the 80's.

Peter rushes Ollie Williams and calls him American actor Will Smith (1968-) and asks him, “what was it like to punch that alien in the face”, this is an allusion to the 1996 big budget Roland Emmerich directed summer blockbuster ‘Independence Day’ in which Will was one of the stars.

Peter then calls him american comedian Eddie Murphy (1950-) and mentions the real incident when Eddie was pulled over in 1997 after picking up a transvestite prostitue.

Then calls him Bernie Mac (1958-2008) and asks him why he died, then calls him Oprah Winfrey (1954-) and Don Cheadle (1964-)

Peter: I'm self conscious about my congressman Barney Frank body

Congressman Barney Frank (1940-) is the U.S. Representative for Massachusetts's 4th congressional district (1981–2013).

TV Announcer: We now return to Robert Mitchum in ‘A Backhand for Sally’
