Considering the situation we're all in right now, here's a rather topical Bruce Cayard animated segment from "Sesame Street" that debut in Season 12 and was animated by Canemaker:

Note that this version has sound effects that were added in the mid-90's.
As a tribute to Gene Deitch, here's his 1984 West Wood adaption of the award winning book, "Why Mosquitoes Buzz in People's Ears" (1975):


excerpt from the Fibber McGee and Molly radio show
Ken Darby's The King's Men sing "I Tipped My Hat (And Slowly Rode Away)"
which they also sung for the Tom and Jerry cartoon Texas Tom.
As a tribute to Christopher Plummer, here's the 1987 Academy Award winning animated short, "The Man Who Planted Trees" which he narrated. Directed by Frédéric Back and based on a short story of the same name by Jean Roberts, it was #44 in the book "The Fifty Greatest Cartoons":

A Quake/Quisp commercial with Elizabeth Montgomery:

I saw this ad in a theater in the early 1980's, 1979 at the earliest:

My dad yelled at me for laughing at the character who only says "Si". Not for it being "racist" but because it was "the highlight of my day". Now I know that it has a pedigree:

(Both sketches were reworked after Jack Benny's TV show went to color. The first one was reworked to reference the popularity of Herb Alpert and the Tijuana Brass. The color versions are posted on YouTube as well.)

The 1984 CBS Saturday Morning Preview special. I actually watched this when it originally aired, even though by then I had joined a Saturday morning bowling league.
I'm mainly posting this because it includes clips from "Rabbit Rampage" and "Duck Amuck" with Bugs Bunny's lines redubbed by Mel Blanc. (And I think he did his famous "sputtering" sound effect that he originated for Jack Benny's Maxwell when Joyce DeWitt's "plane" runs out of gas.)
Also I think I saw Bill Melendez in the background in one scene. I wonder if his studio was used as the setting for this special? It would make sense since The Charlie Brown and Snoopy Show was in production at the time. According to the end credits this special was written by Mark Evanier, so I may contact him to ask him about this (as well as why Mel Blanc didn't get screen credit in this special).

"The Snow Man", a 1940 Terrytoon with original theatrical titles:
Here's the unaired 1963 TV documentary "A Boy Named Chalie Brown" (not to be confused with the 1969 feature film of the same name). This was the first Peanuts collaboration with producer Lee Mendelson. Note the animated is little more limited in some scenes compared to the later specials:

"The Old Fire Horse", a rare b/w Terrytoon from 1939:
For comparison, a 1945 color remake ("Smoky Joe") is here:
Continuing the theme of animated remakes, here's a comparison video showing both versions of Disney's "Orphan's Benefit" (1934/1941) which used the same soundtrack. Note Donald's brief impersonation of Jimmy Durante in the 1934 version which is not present in the 1941 version due to Donald's streamlined design with a shorter bill.

D'oh! That's the one. Thanks. I could've sworn I put the video link on there before I logged off last night. I should've have double checked. 😰

Some 1960's TV Magoos with "Charlie" with their original soundtracks and (mostly) complete opening and closing titles. (Though the prints are faded.) This is how I remember watching them on WGN in 1979 and 1980. (Except for the faded colors.) Note that there are two different versions of the opening, with different sound effects.

Some Bewitched openings with the original sponsor plugs intact, and often different sound effects and orchestration of the music. Announcers include Gary Owens and Dick Tufeld:

(Note that in this opening there's a tea kettle on the stove instead of a frying pan. That's because the sponsor was afraid that viewers would think that it was Aunt Jemima pancakes burning.)

(There used to be an Aunt Jemima opening with an animated Tabitha on YouTube, but it must have been taken down.)

Here's the first commercial for the defunct General Mills cereal, KABOOM:

Tommy Stathes just posted something I just couldn't believe even existed, or even would exist. A black-and-white version of the Looney Tunes main and end titles from the Seven Arts era, as found on a print of Bosko's Dizzy Date (1933).

Bobby Bickert
Just like with the redrawn Looney Tunes, the "bouncing O's" are in perfect sync with Bosko's "That's all folks!", I assume by sheer coincidence.

A print of "Cookin' With Gags" with the original titles:

Recently, for the current "Looney Tunes Show" series, a new stop-motion short with Daffy Duck was revealed at an animation festival in Paris. Like a lot of the shorts, it's based around Clampett. It remined me that Clampett himself dabble in that type of animation while working on the black and white Looney Tunes series in the late '30's/ early '40's. He actually saved some of his animation which was included in the first "Beany and Cecil" DVD. Here the footage with archived article of Clampett from one of his visual talks in the early '80's:
