George Carlin: Again! (sometimes listed as On Location: George Carlin at Phoenix) is United States comedian George Carlin's second HBO stand-up television special. It was filmed in the round in 1978 in Phoenix, Arizona. The show was first broadcast on July 23, 1978. On an episode of Inside the Actor's Studio, Carlin refers to this HBO broadcast as a way to enter back into the popular eye with a mass audience with visual adding to the material.

The opening segment of the show contains pictures from Carlin’s childhood which he narrates over: “I thought we might take a look at some of the pictures from the days when my showbuisness career was just starting.” The narration segues into Carlin waiting backstage to go on. George Carlin begins his routine by acknowledging the audience before diving into his “Goofy Shit” list which includes some new routines: Sandman on a rainy night, large craft warnings, Marine land fish sticks, centipedes, waiters in waiting rooms, evening gowns at night clubs, florescent lights, Kleenex targets, the hats that are not there, frogs legs, emptying the wishing wells, dream credits, why there is no blue food (first performed at the very first episode of Saturday Night Live), skilled and unskilled workers, why we buy flowers, and cleaning the church.

Carlin then performs a new long routine about time, who has the time, and words we use to describe time (“Sooner than you think… sounds spooky doesn’t it?”)

He then sits down to perform an uproarious version of the “New News” routine combining new material with the material from An Evening With Wally Londo Featuring Bill Slaszo and On the Road. This routine is received very well by the audience, including when someone throws him a joint onto the stage. George then does his famous imitation of Al Sleet “Hippie-Dippie Weather Man.” (“Tonight’s forecast… dark!”)

George Carlin performs a more focused version of “Death and Dying” than the one from On the Road. Carlin briefly revisits the opening theme, “Well, somebody’s gotta think of this shit.”

The final part of the routine is arguably George Carlin’s most famous rendition of the “Seven Words You Can Never Say on Television” sketch (first performed on Class Clown), which is the centerpiece of the DVD George’s Best Stuff. The routine is expanded from the famous Occupation: Foole performance. Carlin adds a physical comedy portion in the beginning with “Trial and Error.” Carlin presents the idea that we have more ways to describe the dirty words that we have actual dirty words:

"Someone was quite interested in these words. They kept referring to them: they called them bad, dirty, filthy, foul, vile, vulgar, coarse, in poor taste, unseemly, street talk, gutter talk, locker Room language, barracks talk, bawdy, naughty, saucy, raunchy, rude, crude, lude, lascivious, indecent, profane, obscene, blue, off-color, risqué, suggestive, cursing, cussing, swearing…

and all I could think of was: Shit, Piss, Fuck, Cunt, Cocksucker, Motherfucker, and Tits!"

Carlin admits that the original list was not complete, even by adding Fart, Turd, and Twat. He assures the audience that “some of [their] favorites might make the list this year.” Adding more words to the list: asshole, ballbag, hardon, pisshard, blueballs, tate, nooky, snatchbox, pussy, pecker, peckerhead, peckertracks, jizum, joint, donacor, dork, poontang, cornhole, and dingleberry “Innocent sounding word, sounds Christmasy to me.”

Another hilarious new section is added to the routine referring to the word “Motherfucker” coming off the list due to a phone argument with an English purist calling “Motherfucker” a duplication of the root word “Fuck.” Carlin’s immediate reaction to the purist is “Hey Motherfucker, how did you get my phone number anyway?” The purist convinces him to drop it, but Carlin is now unhappy with the current rhythm of the list (now with cocksucker standing alone as the only multi-syllabic word on the list) happily repeating the old list it in a lyrical manner.

Carlin continues with an extended version of the familiar “Tits” portion of the routine and incorporating the “Cute Little Farts” routine into the mix. After briefly going through familiar jokes referring to turd, twat (“Twat’s twat and that’s that”), prick, and ball. The famous section about the word fuck is longwinded as Carlin reminds people what happened to the word, “We fucked it up.” The routine incorporates more physical comedy. He refers to the famous phrase “Make love not war” wishing he had though of that so he could retire and go to the beach. Coming up with his own phrase “Make fuck, not kill” Carlin explains “I’m not looking to retire anytime soon” which is followed by thunderous applause. Replacing “kill” for “fuck,” Carlin incorporates new references including “Shamoo, the fucker whale” with Carlin swimming away in a panicking manner. His final message is one of love before he introduces his wife, Brenda onstage. Carlin says goodbye to the audience or “Fuck You” before he dances an Irish jig over the rolling credits.
