Ajax, in "American Dicks": "My dad swatted my face with a broom once. Of course, I was eating from the dustpan at the time."
In the episode where King Chicken plans to get revenge on Duckman by educating Ajax so Duckman is no longer able to relate to him, Ajax can be seen giving a presentation on onomatopoeia. Later during a fight between Duckman and King Chicken that carries across the entire school, they end up crashing through a series of signs with the onomatopoeia for the sound effects that play written on them.
This string from "Das Sub" when Duckman first meets the class he has to teach for community service:
Duckman: You're lucky I never hit a lady who makes my Noam Chomsky. Student 1: Degrading sexist remark noted! Duckman: Ohhhhh yeah. Who's real now, Dexter? This scene is real gone, baby. I am, into, it all, dig? Ohhh, hep, very, hep. Student 2: ....Do you need a shot of insulin or something? Duckman: I don't DO that crap. I'm clean. What are you into, hmmm? Shiners? Boom-booms? Rippos? Calistogan canoe wax? Sinuvian swamp weed? Latter-batter? Bud bugs? Spot foxy? Or is... booger-sugar your "lady"?
In America the Beautiful, Duckman and Cornfed search for a model named America, and her former boyfriends who represent different decades of history. When entering a place called Appleville, a black and white town representative of the 1950's, all of the color leaks out of Duckman and Cornfed.
The beginning of Pig Amok when Cornfed arrives at the funeral.
Cornfed:Pant pant, wheeze, deep breath. Pardon my tardiness ladies and gentlemen, I've been vomiting violently all morning, my septum is severely deviated, and I've already passed three- EEEEEYAAAAAAA! Four, very large kidney stones. Also I've got a bitch of an ice cream headache. Well, I'm sure if Harry could see how many of you came out on this solemn occasion, the first thing he'd say would be (Begins convulsing) honey horn dog! Butt...bongo ribbed and lubricated for that feel of real!
Cornfed: Ahem, I'm sorry, that was highly inappropriate. LOOOOIIIIN KING! Rear admiral! Squeal like a pig, REEEEE!
Cornfed:...So, uh, we are here in Harry Leibner's honor. On her! Off her! On her, off her, yee-ha, YEE-HA, YEE-HAAAA!...To share our memories. Memories, mammaries, great big swollen mammaries, meat melons, rib balloons, potent pigs from the past FOR 100 ALEX!
Additionally, it's hilarious whenever Cornfed acts out-of-character and drops his usual deadpan demeanor, which he does in the episode Psyche as well, when offered a case in which he and Duckman have to date two ridiculously large breasted women.
Cornfed: Duckman, we have to go. I need to learn how to awaken the sexual beast that lies dormant in every woman's soul, waiting to transform her into a creature of unbridled passion, pulling at me, tugging at me, yelling TAKE ME CORNFED, MAKE ME YOUR LOVE SLAVE!(Beat) You know, that sort of thing.
After Duckman chickens out and bails on the mission...
Duckman: Did I miss anything?
Cornfed: We went back to their house.
Duckman: Their house!? Details, give me details.
Cornfed: A-frame. Two and a half baths. Exposed brick fireplace-
Duckman: No, you idiot! What happened!?
Cornfed: We played Twister. I lost. (Giggles) Beyond that, I am a gentleman. (Giggles harder) Now if you'll excuse me, I'm off to help Clasette and Fantene learn why men focus on their bodies while they sponge-wash their car in cut-offs. (Giggles maniacally)
The Mockumentary episode American Dicks is pretty much one long Crowning Moment, but a few special mentions are needed. For example, Duckman attempting to come off like an expert detective to the camera, while overlooking or ignoring ridiculously obvious clues and leads to the case of the episode, finding the kidnapped mayor of the city. Among other things, he doesnt notice a picture of the mayor being held hostage by baseball manager Lance Le Francis on a milk carton he's drinking from, and doesnt notice the mayor being dragged kicking and screaming into a van across the street until Cornfed points it out to him.
Cant forget the interview the American Dicks cameraman has with Cornfed.
Cornfed: Have you ever realized you were living in a deep dank abyss, causing you to roam the world for five years until you end up becoming the chef of a tibetan monestary?
Camera Man: I just asked what kind of detective Duckman is
Cornfed: Oh... I have some clothes in the dryer.
"The Amazing Colossal Duckman" features Duckman growing to immense sizes as he gets angrier and angrier. Knowing this would get him out of the house, Bernice deliberately sets him off by things like stabbing his foot with a pitchfork and tying his fingers together. Thus, when Duckman says his goodbyes to his family and sets off for his self-imposed exile, he flicks Bernice off the roof.
Duckman's parting advice to his sons consists of "There is nothing an ointment won't cure."
In "Papa Oom M.O.W. M.O.W.", when three top-heavy women visit Duckman's office:
Woman: What do you do here? Duckman: I look at breasts. Y-and I'm, I'm a detective. Heh heh. But, mainly the breast thing.
Duckman attempting to comfort Miss Liebner at her husbands funeral in Pig Amuk
Duckman: Your husband was a good man who always put his family first. In fact, it was out of concern for you that he concealed his rampant homosexuality! The last thing he said to me was "Duckman, don't tell my wife" *the widow starts bawling* He was protecting you, he was afraid you'd think you drove him to it, but you didn't. He said he stopped caring about you years before he even slept with a man! *Bernice smacks Duckman into a stained glass window*
Bernice: There there, its alright. You can take some comfort in knowing that Duckman will be put in a box and buried six feet under some day too. Tonight maybe, after he falls asleep!
