* "Elvis didn't do no drugs!" BlatantLies by any other name.
* In the Martial Arts episode, Penn, in a ridiculous tie-dye karate uniform, teaches his own pacifist martial arts to children that involves pouring chocolate shake all over your head.
* The "Ouija Boards and Near Death Experiences" episode gets ever more ridiculous; from the ouija board that still works upside down to the people who believe their dog has been re-incarnated three times until, with perfect comic timing, Penn announces "then there's ''this'' fuckin' guy..."
* Professor Best: "We didn't interview Professor Best just because of his last name but we did tell Professor Worst to go fuck himself."
* (whispered voiceover) "''Grilled cheese sandwich'' ... ''grilled cheese sandwich''... IT's A GRILLED FUCKING cheese FUCKING sandwich!"
* The Area 51 episode has a hilarious spoof of the whole "alien conspiracy" with the RunningGag of "Box 51" in which Penn claims a box Teller is holding contains Hitler's brain due to Teller neither denying or confirming said brain is in the box.
-->'''Penn:''' (Box begins to twitch) Not only does Box 51 contain Hitler's brain, but it can dance! (smoke emits from the box and lights flash from inside as well) And it's on fire!
* And then in the Conspiracy Theories episode, Penn and Teller depict what it would look like if the Apollo moon landings were staged on movie sets as conspiracy theorists claim.
-->'''Penn:''' CUT! Jesus fucking Christ, Neil! How many times do we have to try this? "One small step for ''A'' man", not man. A man! And that's YOU! Everybody take five. Neil, practice your fucking lines! [to Teller] Ooh yeah, let's use ''real'' pilots. I wanna use ''real'' pilots! [to the camera] Faking the Moon Landing is easy. You need dirt, wardrobe, a sound stage, a lot of black paints, and some stupid suits. The hard part is shutting people up. It's been ''36 years!''[[note]]The episode was recorded in 2005.[[/note]] You'd think the technicians, and prop people, camera people, directors, everyone who works at NASA, and the Jet Propulsion Lab in Pasadena, and all the nice folks at Cape Carnaval in Florida, plus members of the US Congress and the White House all shut up about this amazing cover-up for all that time? The Government couldn't even fucking cover up a break-in to a psychiatrist's office in a fucking cheesy hotel! Watergate is the answer to all this shit. If they couldn't cover that up, they fucking can't do anything.
* In the Video Games episode, one guy claims that FPS's "train" kids to shoot. They wordlessly tear apart the idea that mainstream video games can train you for ''anything'' by showing Teller calmly playing Wii Tennis, then having a real tennis player hand him a racket and serve him a ball. It doesn't even look like Teller ''sees'' the ball.
* From the Martial Arts episode:
-->'''Penn:''' (on the subject of a cynical karate studier making the art of breaking boards seem like nothing more than a parlor trick) Okay, if you're gonna badmouth Sensei Mike's powers, you better stand up and start chopping some wood. Quit acting like [[TemptingFate your wife could do it in your garage with your neighbor]]. (scene cuts to [[YouJustHadToSayIt immediately what Penn just stated]]) Heh heh... oh shit. That's your wife, isn't it? In your garage? With your neighbor?
* Music/TedNugent discussing PETA. LargeHam doesn't even begin to describe it, he devours more pork in 30 seconds than Penn would have in his life.
** Also during the PETA episode: when they meet activist Rodney Coronado, who had fire-bombed several animal testing labs, [[AffablyEvil was polite and friendly in his response to Penn Jillette's call]]. This prompted Penn Jillette to remark "[[YourApprovalFillsMeWithShame Cool guy, likes us, and likes our show. Too bad he's a]] [[PrecisionFStrike fuckin']] arsonist."
** Penn points out that a chicken in the studio is [[ImAHumanitarian eating chicken.]]
* Penn (when speaking of Pope Benedict XVI): "Now let's get this party started, with the man who puts the "athol" ([[DontExplaintheJoke pronounced like asshole]]) in Catholic."
