In another episode, when Peter launches himself with a catapult. We get a scene of a man in a room, going over a list of all the precious, easily breakable things that are in that room (including a hemophiliac baby). Of course, Peter lands... right outside the window to the room, and proclaims "Those are all nice things!"
A more classic example happens when Peter tries to deviate a parade to his house for Stewie's birthday party. He waits ahead at a fork for the parade to come holding a Detour sign... then he slams it on the parade leader's head, knocks him out, steals his uniform and leads the parade to his house.
In "Brothers & Sisters", Mayor West tells Carol he has aides, leading Carol to think West meant the STD. West points to two men that are his aides and then says they have AIDS.
There's another episode where Adam West is looking for a sign to warn people about his ferocious dog. You would think he's looking at the "Beware of Dog" sign, but he's actually looking at the "One Way" sign, so that people will know that there's only one way they can go to get away from his dog.
In "Brian in Love", Brian confesses to Peter that he's in love with Lois. Peter looks at him and says, "Oh my God!" Then he pauses and adds in: "You can talk!"

In an earlier episode, there's a Cutaway Gag where Peter cuts a cake but ends up accidentally slicing a woman inside the cake (who was supposed to surprise the guests by jumping out of it). Peter yells, "Ah, crap!" but not because he killed the woman; it was because the cake was coconut flavor.
"Killer Queen" has a Running Gag where Brian comes up with many creative ways to get Stewie to see the giant robot on the cover of Queen's News of the World album, which scares him to death. At one point, Stewie walks into his room and sees an unopened Jack-in-the-box. At this point, Stewie thinks he's onto Brian thinking the robot will pop out. He turns the crank anyway, and it turns out to be just a normal clown. Stewie sighs of relief, but turns around only to see the that Brian painted the robot on his wall.

At the end of "Baby Not on Board", when Stewie sees the rest of the family returning home after they accidentally leave him home, he exclaims "Mommy! Daddy! Chris! Dog! Brian! They're home!" Ordinarily he uses "Dog" to refer to Brian, but due to Rule of Funny here he used it to refer to Meg.
In "If I'm Dyin', I'm Lyin'", before Peter walks into a TV executive office, a woman at the desk says, "You can't go in there." Peter responds, "Oh yeah? Watch me!" and then he hits a brick wall.

In "Running Mates", Lois ends up winning the position of school board president by default due to her opponent quitting, but she refuses to rehire a beloved teacher of Peter's from when he went to high school, so then we then see him lifting an ax over her head and saying, "Well, then I'm just going to have to kill you..." then the scene transitions to their front yard as he uses the ax to pound in his own lawn sign, stating "...in the race for school board president."
"Dammit Janet!" has Peter talking at the bar with his friends and griping how Lois wants a job. He then says, "I've got a job for you, baby; Right! Here!" As he points to his penis while saying it and then continues on, explaining, "See? The damn zipper's been broken for a week! I was hoping you could fix it."

"Brian Does Hollywood" has Peter trying to invoke a Quip to Black when learning that Stewie's successful audition has won him and the family a trip out to Hollywood to appear on Kids Say The Darndest Things and expressing how people always say something clever before a commercial break.

Later on while in L.A., Peter finds himself getting beat up by the LAPD, only for it to be that he and the cops were pretending to assault him for a photo that Lois was taking of the trip.

Then a short time later at home, Peter is bummed out only for the principal to call him up and say that he now, out of the blue, loves his plan and will go through it.note The plan being that he would pretend to be a hip new student to try and scare the kids away from licking toads to get high
