People have listed some of my favorites: Feast, Presto, and La Maison en Petits Cubes. I don’t think I could name just one favorite but here’s one that hasn’t been mentioned: A Single Life
I won’t link it but another great one is “The Fantastic Flying Books of Mr. Morris Lessmore”. Nobody gets more pathos out of Pop Goes the Weasel than that short.
Mouse Menace with Porky. This is a good one to watch while herbally enhanced. Stalling syncs the music to the action perfectly.
Glad to have been of assistance, @CalMeacham.
Cheers!
The OP’s offering reminded me of David Lynch’s fun “Dumbland” shorts.
Myself, I was thinking more along the lines of Scotty of the Antarctic, featuring humans fighting lions, and the penguin…well…more on the gigantic (and tenatcled) side than condescending.
This!
Here’s the entire short film (unmute the audio):
Stupid me didn’t even think of including Bugs Bunny cartoons, so I have to add the Robin Hood short. I roll on the floor no matter how many times I see it. “Don’t you worry, never fear, Robin Hood will soon be here.”
Ha. Love me some Richard Condie. : ) This one is kinda long but definitely a favorite.
What on Earth!
Another NFB classic, from 1965.
Aah,that’s mine as well.
That and the Aardman shorts. Creature Comforts, for instance.
While we’re at it–To Be:
Is this Good or Bad?
“Aeon Flux” (~10 min, no dialogue)
I love all the Schiele-type stuff.
Yes. 
My favorites are the previously mentioned “Duck Amuck” and “Baseball Bugs”, plus one I saw back at college in the 1980s that I cannot find now. It was hilarious. It was a parody of Star Wars, featuring household appliances, (clothes irons, toasters, electric shavers, etc.) flying through space like spaceships firing at each other in an epic battle. It was a riot, but my google-fu is poor and I cannot find it here now today.
Hillbilly Hare
And, of course, Duck Amuck and What’s Opera, Doc?
Round about half a century ago, the National Film Board of Canada released “Hot Stuff,” an amusing fire safety short. My father would bring home a projector from work for our birthday parties. Back in those days, you could get 30 minutes of films for free from the library. I still have fond memories of choosing this film year after year.
Hardware Wars, my friend. “You’ll laugh, you’ll cry, you’ll kiss three bucks good-bye!”
(The original version has been slightly soup-ed up – it’s THE SPECIAL EDITION!! I’m not sure this one’s it.)

Apparently another Canada NFB. Has some seriously catchy material…“Sawing for Teens,” “Stop shaking your eyes!!” etc.
I already did a post, but wanted to put up an honorable mention. This isn’t my favorite, but it is one of the ones that moves me.
There Will Come Soft Rains, based on the short story by Bradbury, with Soviet era animation and dialog. It’s moving, as well as depressing story in the original. While the animation is not 100% faithful to the original, it still evokes the feeling of the story well. While we’re less worried about nuclear annihilation these days, it still haunts me at times.
