Meeko, see post #16 in this thread.
Daffy Duck from “Duck, Rabbit, Duck”…
“Shoot me again! I enjoy it! I love the smell of burnt feathers… and gun powder… and cordite. I’m an elk! Shoot me! Go on!! It’s elk season! I’m a fiddler crab. Why don’t you shoot me?! It’s fiddler crab season!”
Not quite as venerable, but the Iron Giant jumping in the lake. Hogarth ends up at the top of a tree, Dean half a mile away, still in his lawn chair. The exchange between Dean and the farmer driving past was the capper.
MY absolute FAVORITE cartoon of all times is the Loony Tunes with the frog in the corner stone . I have not seen it in years , but would LOVE to have it on video to watch whenever I feel down .
It begins with the construction worker tearing a building down , and locked in the cornerstone is a frog . As soon as he frees it , the frog leaps up singing “Hello my honey , hello my baby , hello my rag-time gal…” . The worker sees dollar signs , and tries several venues to exploit the frog’s talent , but of course , all the frog will do is lay there and say “Ribbit” . The poor worker looses his mind over this , and ends up sealing the fog into another cornerstone of a building going up .
Fast forward to THAT building being town down . Another construction worker opens the cornerstone , and again , the frog leaps out singing “Hello my honey , hello my baby , hello my rag-time gal…”
And so it begins again… 
“One Froggy Evening”
with, of course, Michigan J frog.
Be careful what you wish for… You might just get it. And really, are you going to enjoy it so much on the 85th time? You might. I don’t know too much about you.
Most of my favorites are from the old-time Warner cartoons featuring Bugs Bunny, too many great scenes to pick one from those.
There was a scene in one short with Daffy Duck and another regular (maybe Porky) which stands out my mind. They are in a hotel room and Daffy is recounting some weird night he had, laughing his ass off after every sentence. Near the end he says (from memory) “…and the little guy got thirty days for kicking a cop,” then he collapses in self-induced hilarity. Made me laugh as a kid, but even more so now as a semi-adult with some experience of night life.
The entire 7 minutes of Tex Avery’s “Rock-a-Bye Bear” (1952), but especially the bit where Spike the dog shuffles along on his buttocks with a pepper-pot on his nose.
Daffy Duck is let out of a freezer.
In a voice that sounds like an ecstatic acid-head describing the afterlife he says, "What do you know? The little light! It stays on!!
I haven’t seen it in decades, but it is still my favorite cartoon moment.
Kenshin Seisouhen episode 3, when
Kenshin dies, and his cross-shaped scar disappears.
It’s beautiful - everything in the entire series from beginning to end was to build to this single moment. Oh, and sad, too.
I always loved Pepe Le Phew. I felt so sorry for that poor little black cat he was always chasing!
She has a name, y’know. Penelope.
Too many to mention, but this one gets me just thinking about it:
Somehow, Sylvester is involved in the Foghorn-Dawg-Henery wars. Henery Hawk is hiding in an eggshell and has ticked Sylvester off. He gets a hammer, heaves with passion, winds up, lifts the hammer, yowls in triumphant rage, and just then Henery pops out and screams “STOP!”
Sylvester drops his hammer. He shivers uncontrollably. He pulls his hair out. Then - this is the good part - he starts yanking his tail to pull his head back into his neck. It’s the funniest thing ever. He looks like he’ll do it forever until Henery clobbers him with a shovel.
The one where the tough guard dog “adopts” a cute black kitten…unbeknownst to his owner…and goes about his usual patrol with the kitten snugged in the folds of fur on his back.
The kitten falls onto the cookie batter, and the dog is kicked outside when he attempts to bring attention to himself with a faux mad-dog routine with whipped cream all over his mouth.
He squirms in agony as he sees the the dough roller-pinned, cookie cutted, and baked.
The owner, feeling the dog may now be let in again, placates him with a cookie…in the shape of a kitten. He accepts the cookie, and his heart absolutely dies.
He places the cookie in the snug of fur on his back as the tears flow like a river…
…and the kitten comes out of her hiding place and licks him on the nose.
His grief becomes pure joy and love as he holds her close.
No, no, no, it must be: “Kum by Yah, it never hurts to help!”
Yes, I still laugh at this.
From Baseball Bugs:
One, two, three strikes, yer out! One, two, three strikes, yer out! One, two, three strikes, yer out!
I still call a really good change-up a “Bugs Bunny Slowball.”
Other people have thrown in anime, so I will, too.
For beautiful moments:[ul][li]The Shinji and Kaworu scenes in Evangelion, where they’re talking about human nature, beauty, and love – some of the most beautiful and thought-provoking scenes in animé.[/li][li]Almost everything in the** X** movie is eye candy, even if the plot was too condensed from the manga to make much sense. What especially stands out is the scene Kanoe shows Kamui to get him to help them wipe out the human race so that nature will survive. It’s an image of Tokyo City Hall, half-immersed in a lake, surrounded by nature at its most verdant and beautiful.[/li][li]The fascinating (and disturbing) final battle in Revolutionary Girl Utena – a sort of fairy tale gone horribly wrong – is amazing to watch.[/li][li]The battle scenes in an early episode of Yami no Matsuei/Descendents of Darkness, when Muraki and Tsuzuki first fight. Tsuzuki and Hisoka join their powers, and Tsuzuki summons up one of the four gods typically mentioned in Feng Shui, the phoenix Suzaku, to battle Muraki’s dragon in an abandoned mansion which gets rather quickly demolished.[/li][li]The first arrival of the spirits at the bathhouse at the beginning of Spirited Away.[/li][li]A number of nature scenes in Princess Mononoke, especially the transformation of the Forest Spirit. [/ul][/li]
For comedy:[ul][li]Any two minute section of Excel Saga is bound to be side-splitting. Especially the scenes where the dog (who’s been designated as emergency food supply and knows it) almost escapes her. The closing credits, where the dog sings about its sorrows while Excel dumps salt on him, are pretty funny, too.[/li][li]Gravitation is full of funny moments, too, thanks to Shuichi’s single-minded obsession and talent for transformation. He’s funniest interacting with Ryuichi. Funniest is probably when Shuichi is trying to get away from him, and Ryuichi, in full chibi mode, transforms into a vampire and leaps off a building onto him.[/li][li]The magic mushroom scenes in Cowboy Bebop are hilarious.[/li]A recent favourite is the scene in Kyou Kara Maou, 2nd episode, where Wolfram insults Yuuri’s mother, and Yuuri slaps him on the left cheek, especially the look on his face when he finds out that he’s used a traditional method to propose marriage to Wolfram, and can’t get out of it. The scene where Wolfram showed up in his bed in a nightie was pretty funny, too.[/ul]
This is the one I came in here to post. “Feed the Kitty” is what it’s called. The first of four cartoons with Marc Anthony and Pussyfoot. The scene with the cookies has always made me laugh until I cried.
And Disney’s homage to this scene in Monsters Inc. would probably be my other favorite cartoon scene.
As a kid, I always loved the cartoon moments when a character walks off the edge of a cliff, but doesn’t fall until he looks down and realizes there’s nothing under him.
As an adult, I see that moment occurring in people’s lives all the time.
