A drunk Lois on all fours telling Peter to "get on". This is at the red carpet premiere for the movie, mind you.
Lois: Peter. Peter. (whispers) Get on. Peter: Son of a bitch.
The "incest episode" from the DVD extra:
Brian: WRONG! It's WRONG! (pounds table)
78. Stewie B. Goode
This:
Peter: You know what really grinds my gears? You, America! Fuck you! Diane?
After his night out with Brian, Stewie finds that he apparently had a one-night thing with Roger Moore that led to him having "Property of Roger Moore" written on his stomach (in the TV version, he simply has a handkerchief with the initials "RM" on it, leaving him wondering what they stand for).
79. Bango Was His Name Oh
At the electronics store, the guy selling Peter and Lois a TiVo uses its remote to fast forward in time, during which Lois performs the Heimlich maneuver on Chris, who was choking because he somehow swallowed a camcorder.
To make sure no one notices they're gone, Stewie has two robots of himself and Brian:
Robot Stewie: (in Machine Monotone) Damn you, vile woman. Blast. What the deuce? Robot Brian: (also in Machine Monotone) I am a tool. Stewie is much better than me at everything, including arts and crafts and the guitar. I have no friends.
While pursuing his future self, Stewie jumps through a window and is replaced by a less-than-convincing stuntman.
80. Stu and Stewie's Excellent Adventure
After following Stu into the future, Stewie is disappointed because he thought he'd be the supreme ruler of the world away from "that house full of idiots". Cut to Peter, Chris, and Brian on the couch, where Brian unwraps a candy bar and throws it to the ground, causing Peter and Chris to knock themselves out when they hit their heads trying to grab it at the same time and Brian rests his feet on them.
Stewie's defacement of Brian's grave (he crosses out Brian's name and writes "Douchebag" on it):
Stewie: Oh, this is fantastic! Stu: Well, that's not very appropriate, Stewie... Stewie: Well, of course, it is; I loathed that know-it-all flea-bitten mutt! Stu: No, no, it's just that the meaning of that word has changed, ever since President Douchebag.
When Stu shows Stewie the former's version of Rupert, Stewie wonders why Rupert's leg has been stitched back on, then remembers the reason: he and Brian were debating whether a flat tax favors the wealthy and Stewie called Brian retarded, so Brian nonchalantly took Rupert and ate his leg with a knife and fork. When Stewie demands it back, Brian assures him that he'll get it back.
Brian in Heaven:
Brian: Wow, I can't believe I'm in heaven and drinking with Ernest Hemingway, Vincent van Gogh, and Kurt Cobain. But still, it feels like we all got here a little earlier than we should have. Ernest Hemingway: Yeah, well, I collapsed under the weight of my own genius and shot myself. Vincent Van Gogh: I could not reconcile my passion with the way others were living around me, so I shot myself. Kurt Cobain: I hated the thought of my music becoming part of some bland corporate mechanism, so I shot myself. Brian:(sheepishly) Yeah, I, uh, I got into the garbage and ate some chocolate.
When Stu and Stewie return home after Stu loses his job and find Stu's apartment on fire, one of the firemen lampshades the irony of the fire being caused by the stress relief candles that Stewie left lit.
When Peter and Lois are moved into a retirement home, they find Cleveland, Quagmire, and Joe already there. Cleveland previously had a stroke and now talks very slowly, while Bonnie died before Joe and he's now using her legs to replace his, giving him his mobility back.
