Against his tightwad instincts, Scrooge must spend several surplus million dollars when he runs out of vault space to store it. After hours of what is, for him, torture, Scrooge discovers he's earned more money all the while, so he still has the surplus regardless! His response is priceless.
The boys' repeated failures with their animal calls in "The Lost Mines of King Solomon".
Seriously, everything regarding the Black Knight and his accent. Especially the ending of "The Black Knight Glorps Again":
Scrooge: (after Donald's read a letter from the Knight) Why are you reading with his outrageous accent?
Donald: Because he even writes with that outrageous accent.
The strangeness escalation of Donald's TV shows in "Guardians of the Lost Library", where the hero's vehicle always bursts into flames for no reason. Be it a car.. .A speedboat... A horse... Even a comet.
In "Dream of a Lifetime", the Inception-like dream machine makes any sound Scrooge hears during his sleep will appear as a RELATED object in his dream. Note the word "RELATED"
Every time the dream shifts and Scrooge Discovers Donald his response is: "Nephew?! What the @*%# are you doing here?!" Even when Donald runs into him as a 10 year old shoeshine boy.
In the anniversary celebration A Little Something Special, Scrooge is bored out of his mind at a celebration in his honor, held away from his Money Bin. The speaker is a tall pig, but looking down, Scrooge sees that he casts Flintheart Glomgold's shadow. His next thought balloon is presented as a rebus:
Sadly, the rebus is not continued when he learns the Beagle Boys have also joined forces with Glomgold and Magica.
It's even more hilarious when Scrooge then runs from the celebration, and Glomgold, in his disguise, desperately tries to beg the very confused Chief of Police to shoot the guest of honour down.
In The Black Knight, Scrooge tried everything he can to stop the titular Black Knight. He asked the National Guard to launch a missile strike against The Black Knight, and...
Soldier: Hmph! Scrooge McDuck just called and ordered an anti-tank missile for home delivery! What's he think we are, a pizza joint?
Officer: Push the button, man! McDuck's taxes pay for 97.3 percent of this entire installation!
"Escape from Forbidden Valley": Donald gets abducted by a large female dinosaur who thinks he's her baby. Parts of her treatment includes shoving worms down his throat to feed him before thinking a solution to end his screaming would be to make him sleep. Donald keeps protesting vividly as she places him on some vines shaped like a hammock, only to fall instantly to sleep once she starts rocking him. Later she finally gets tired of his screaming and... decides to spank him. Poor Huey, Dewey and Louie appear just in time to witness it.
Huey: Is that hadrosaur doing what I think she's doing to unca Donald?
Dewey: Giving him something he mighta needed since... "since dinosaurs ruled the Earth"?
The Dick Kinney/Al Hubbard story Fall Guy starring Donald and Fethry is pretty much one nine-page-long CMOF: Donald and Fethry are on a vacation by Niagara Falls, and Fethry keeps trying to go over the falls in a barrel, completely unaware that this is against the law. Through various accidents and mishaps, both the guard at the Niagara Falls◊ and Donald◊ end up in barrels and going over the falls, leaving Fethry to lament: "Everybody gets a turn but me!"
One four-page William Van Horn story has Donald and Jones trying to stop their fighting by simply ignoring one another. This goes about as well as you could expect, particularly when both of them begin to suspect that the other isn't doing his fair share of ignoring. It escalates to what looks to be a really huge fight — and then, the story's last panel cuts away to a police car driving at top speed down the road with the police radio annoincing: "Calling all cars! Calling all cars! Two neighbors ignoring one another on Elm Street! Proceed with caution!"
One story has Donald enter Bolivar (called "Bernie" in the story) in a talent contest for dogs, betting a month's dishwashing with Huey, Dewey and Louie that he'll win. When Bolivar is too lazy to be trained, Donald decides to cheat by outfitting him with a special collar made by Gyro Gearloose, one that makes Bolivar copy all the motions Donald makes. Come the talent show, Donald is all set to make Bolivar do an elegant dance on-stage — but accidentally hits his head and knocks himself out, causing Bolivar to lie completely still on the stage for the entire time he's on, to the boos and jeers of the audience. The story ends with Donald and Bolivar (still wearing the collar) both washing dishes, using the exact same motions, and glaring at one another.
An Italian comic parodied Twilight. Daisy wrote it with Brigitta as an assistant/editor. It features Donald as "Edward Duckullen" and Daisy as Daisybella. The entire comic is essentially a Crowning Moment of Funny, but here are some particularly funny things:
Magic Brigitta. Since Scrooge features into the story as Charlie Swan, she repeatedly tries to insert herself into the story and successfully woo him. Daisy no-sells every such attempt, and they get sillier each time.
Fethry Duck as Carlisle. He is The Load here, but everyone dismisses it as just him getting senile after 300 years.
Another Italian comic has this exchange between Scrooge and Gyro:
Scrooge:(storming into Gyro's workshop) Gyro! I need your help more than ever! Gyro: Don't tell me it's your spats again? Buy a new pair, for crying out loud! I've repaired your old spats twenty times! Scrooge: It's not the spats. Gyro(working himself up to a frenzy) They can't be fixed again! I'm only human! There's a limit to what I can do! Scrooge: It's not the spats! I want you to send me back in time to 1775! Gyro: What? That's all? (instantly calm again) I thought you were going to pester me about your spats again.
One story featured Grandma winning an "all-rest vacation". Gus asks if he can come with her... to give her the good example, because he doesn't think she is able to rest. He then dares her to go one single minute idle hands. Cue her staying in place cleaning the floor by using her foot and a rag.
The exact same scene is redone with the roles reversed: Grandma dares Gus to stay awake for one single minute. Cue him standing upright, eyes open, snoring.
Then Donald and Fethry come to the farm to take care of it along with Gus. As the bus with Grandma is leaving, Fethry turns to "go combing the potato tree" with a rake, Donald is knocked out with said rake, and Gus is again asleep.
Grandma:*from the bus* LET ME OFF!
And finally... rolling pin-fu. Seriously.
The Italian saga Fantaleggende, published on the Italian "Topolino" weekly. Set in the middle ages, it tends to alternate normal or even epic moments with rather crazy things:
The narrator. A minstrel whose audience will pepper with eggs, tomatoes and other things (including a cake. That he ate) when he takes a pause between a chapter of the current story and the next or starts a new story in the old setting (the audience wants something new). He also has troubles rhyming his narration-And was once caught plagiarizing The Betrothed reading directly from the book.
The first one is too frail, and breaks after tripping on a rock;
The second one is tougher and tracked. On the other hand, it can't cross rivers or jump ravines;
The third one is winged, to jump over obstacles. And too heavy;
The winged one gets modified with the addition of an energy crystalof alien origins, so that, with a little run-up, it will jump over obstables. Donald decides to play it safe, so he takes a long run-up... And lands on the moon;
In the third and final story, the knights must go and fight pirates, but the mechanical horse is out of commission. Donald needs another steed, and jumps on Gyro's flying carpet. A broken flying carpet. The only reason he doesn't get on the moon is that he crashes on a communication device an alien traveling salesman was sending down on Earth, with Donald quickly mistaking the salesman for a genie due the lamp-like form of the device and the hologram making him look like a genie. The alien only humours him due the need to sell his merchandise, as he has his ship's hold still half-full...;
Donald's first wish is, of course, a steed that won't unsaddle him. The alien has him steal the white elephant of a child sultan traveling to reach his realm.
In the final story, Gyro invented a machine to multiply king Scrooge's coins. As it's actually a slot machine (not that he knows), you can guess how it goes.
Later the alien salesman finally reaches Scrooge's castle, and his merchandise includes a slot machine. That he calls the one-armed bandit. Scrooge gets pissed.
In the second story, Pete is called Bronze Leg, but everyone calls him Bronze Face-Italian slang for someone shameless.
Whenever evil wizard Black Spot contacts his Dragon Pete from the moon through apparitions in fire or water, the apparition medium hits Pete.
In a 'classic' Paperinik story (that is, not one of the Paperinik New Adventures series), Rockerduck and Brigitta are talking about their troubles with Scrooge, when Rockerduck starts crying out Fyodor Dostoevsky's name, and we get this pearl:
Brigitta: "Poor boy! Too much stress, you know? He cracked!"
Rockerduck: "Ignore her! I'm not crazy! It's so easy! Dostevsky! Get it?"
Rockerduck: "Dostoevsky! The Russian writer! The author of-"
After solving Magica's subplot and recovering the cash of the Money Bin, Scrooge and his family and allies plan to recover the rest of his fortune and the Money Bin, but Rockerduck and Glomgold currently have it and are about to raze the Bin and Killmotor Hill and their plan needs time. How do they get it? Easy: Fethry gets himself hired in the demolition crew. Cue Smash Cut to Fethry saying to a very pissed foreman that he's not coming closer because he doesn't want to get his feet in the quickly drying concrete that has trapped all the workers.
