Nero Wolfe / Funny

Novels:

At the end of The League of Frightened Men, a novelist Wolfe has crossed vows that he will inspire a character doomed to suffer a violent death in his next book and stalks out of the room. Both Wolfe and Archie get in a zinger at each other as a result.
Archie: I had intended to go to a movie after lunch, but now I can't. I've got to work ahead. I've got to figure out certain suggestions to make to Paul Chapin for his next book. My head is full of ideas.
Wolfe: Indeed, Archie. Your head full of ideas? Even my death by violence is not too high a price to pay for so rare and happy phenomenon as that.

Too Many Cooks

The local DA has been romantically pursuing a girl who Archie has also taken a shine to... and unfortunately for the DA, he arrested the girl's father, one of the Supreme Chefs of the title, for the murder of one of the other ones. Much to his mortification, this has resulted in one hell of a cold shoulder, as Archie is amused to note at one point:
My friend Tolman got it right in the neck, or rather he didn't get it at all, when Constanza Berin came in and he went up to her looking determined, and spoke. She failed to see or hear him so completely that for a second I thought he wasn't there at all and I had just imagined it.
The book has plenty of amusing World of Ham moments from the gathered chefs, including one stating that if it was possible for him to resurrect that Asshole Victim just by lifting his finger, then he would shove his hands as far down as he could.

Some Buried Caesar

Wolfe being trapped on a boulder by an angry bull at the beginning of the book.
Archie is thrown in jail and starts a prisoners union just for the hilarity of it, with demands like "Collective bargaining on all controversial matters except date of release and possessions by out members of objects which could be used for attack or escape", "Abolition of all animals smaller than rabbits", "Daily Inspection of bedding by a committee of public-spirited citizens, with one member a woman" and "Food. (Food may be defined as nutritive material absorbed or taken into the body of an organism which serves for purposes of growth, work or repair, and for the maintenance of the viral processes). We don't get any."
Lily directs Archie to some fricassee prepared by a woman whose husband left her four times for her bad disposition but always came back because of her cooking.
[T]he first bite, together with the dumpling and gravy, made me marvel at the hellishness of Mrs. Miller's disposition, to drive a man away from that.

At the denouement, Nero Wolfe clad only in his pajamas descends the stairs rather than the house elevator to the first floor and takes his chair at his desk in front of Archie, Theodore, and Fritz, and gives this speech, which Rex Stout clearly had fun writing.
Wolfe's glance went from him to Fritz, then to me, and he said slowly and clearly, "I am a brainless booby."
"Yes, sir," I said cordially.
He frowned. "So are you, Archie. Neither of us has any right, henceforth, to pretend possession of the mental processes of an anthropoid. I include you because you heard what I said to Mr. Hombert and Mr. Skinner. You have read the reports from Mr. Bascom's men. You know what's going on. And by heaven, it hasn't occurred to you that Miss Gunther was alone in this office for a good three minutes, nearer four or five, when you brought her here that evening! And it occurred to me only just now! Pfui! And I have dared for nearly thirty years to exercise my right to vote!" He snorted. "I have the brain of the mollusk!"

When Wolfe resurfaces after disappearing for many months, he needs a safe place to bring Archie up to speed on what he's discovered and been doing. He winds up escorting Lily Rowan to her home, under the pretense of a tryst with her. When she sprays him with her perfume in the back seat of a car to add to the plausibility of the scenario, his reaction is delightful.

Wolfe and Archie's disguises, especially when Wolfe quips that he considered making Archie a deaf-mute to explain his inability to speak the local language. Wolfe's constant refusal to refer to the capital as Titograd (and how he incorporates that into his character) also count.
- Earlier in The Black Mountain there's a small slice of Black Comedy following the tragic murder of recurring character Marko Vukcic, when Archie observes that despite the many decades Wolfe has spent investigating murders in New York, he needs detailed directions to find the city morgue.

The book begins with Archie reading poetry verses from a big contest. Wolfe smugly reveals the answer to the riddle contained in one verse but angrily goes silent when Archie recites a tougher one (which an Insufferable Genius suspect later easily solves). Wolfe correctly deduces that Archie is trying to annoy him into sending Archie out of the house for the evening so he can go on a date without having to ask for an evening off.
That's the trouble of working for and living with a really great detective.

While Archie is undercover at a clients home, Wolfe has Orrie Cather pretend to be Archie when the suspects come by his office. Orrie takes no small amount of pleasure in this, while Archie is less than amused. Later, when Orrie's cover is blown, Wolfe tells him to stop pretending, because "One Archie is enough."

After being vexed by a client's irritability, stupidity and pompousness, Wolfe leaves the man speechless by snapping "How the deuce did you get to head a large and successful corporation?"

Wolfe — who hates women to the point of leaving his office in panic if a female suspect cries, and refuses any personal contact at all — instructs Archie to find a nightclub singer named Julie Jaquette and bring her in for questioning. When she arrives, she immediately struts up to Wolfe's desk, performing an improvised cabaret routine (the lyrics begin, "Big man, go-go, big man, go big!") He stares at her, completely befuddled, then accuses Archie of having staged it. She interrupts to tell him that "Nobody suggests anything to me!" Wolfe is intrigued, continues the conversation, and eventually shows open admiration of her, having recognised that "your opinion of our fellow beings and their qualities is somewhat similar to mine."

Wolfe's hilariously futile training regimen at the beginning of World War Two, when he wants to enlist in the army as a common soldier. Apparently it counts In-Universe as well, as Theodore mentions that the boys on the street laughed at Wolfe when they saw him.
Archie realizing that he did temporarily send a killer (who he thought was innocent due to an alibi) out of town on the army's dime and trying to figure out how to justify that in his report.

Hattie Annis, the client in Counterfeit for Murder, is a Cool Old Lady who embodies the 1960s equivalent of "gives no fucks."
- In the same story, one of the suspects, a struggling actor, is reluctant to admit that his alibi is a babysitting job.

Multiple books

Any time Archie pokes fun at Wolfe by copying his Purple Prose to a mystified bystander (it happens fairly often). A paraphrased example from Too Many Cooks:
"Beats me. Must have something to do with the guest being the jewel on the cushion of hospitality."
