Arthur uses the Two Shorts format, with short live-action fillers in between: "And now a word from us kids!"
In some of the newer episodes, "A Word from Us Kids" was replaced by "Postcards from You!".
The Beatles animated series was ABA, with A being the actual cartoons and B as a sing-a-long with two Beatles songs and introductions for each.
The second season of Captain N: The Game Master ran an ABA format, despite Captain N not technically being a short, with a 22-minute Captain N episode being framed by 11-minute Super Mario Bros. 3 episodes over the course of an hour. The last season was instead Two Shorts, with a Super Mario World cartoon and an 11-minute Captain N cartoon (usually one of the 22-minute episodes from the earlier seasons butchered into 11 minutes).
Time Squad mostly had two shorts (much like most other original Cartoon Network programming under the "Cartoon Cartoons" brandnote and a lot of the current Cartoon Network programming, though those cartoons are just packaged as two-short cartoons in daytime reruns. Whenever a new short comes on Thursday, the network airs the new short first, followed by a repeat of the last rerun that came on...unless, like the Regular Show episodes "Exit 9B," "The Real Thomas," "Skips' Story," and "Brilliant Century Duck Crisis Special," there was a full, 30-minute episode that can't be broken into two parts, save for Cow and Chicken, which had an I Am Weasel cartoon in between two Cow and Chicken cartoons until I Am Weasel was spun off to its own show), but the seventh episode of season one had three shorts ("If It's Wright, It's Wrong," "The Time Squad Recruitment Ad," and "Killing Time.")
Cool McCool followed the ABA format with B being Harry McCool.

The "Anthology of Interest" episodes of Futurama, as well as "The Futurama Holiday Spectacular", "Reincarnation" and "Saturday Morning Fun Pit".
Freakazoid! used this format for its first season, but it wasn't really ABA, or ABC, more like ABZ, DFA, or WTF, but switched to full 22-minutes episodes for its second season.
Which was the setup for a Brick Joke for the Animated Actors of the other superheroes to show up and complain about not getting any airtime.
Garfield and Friends, ABA with U.S. Acres, also known as Orson's Farm overseas and on the DVD cut. Originally aired in an hour-long form on Saturday morning, making it a Six Shorts format, but it was really two Three Shorts episodes grafted together.
In between the shorts most of the time would be "Quickies". There were three kinds: as mentioned above, there was a "Garfield Quickie" based on the Garfield strips, a "US Acres Quickie" based on the U.S. Acres strip, and a special kind named "Screaming with Binky", to inform viewers that the show wasn't over in the usual half hour, and starred Binky the Clown.
The first season was only aired for a half-hour. Starting with Season 2 onward, the show was aired for an hour.

The Scooby & Scrappy-Doo/Puppy Hour had Three Shorts as the first half of the program, with two episodes of Scooby-Doo and Scrappy-Doo and one of Scrappy and Yabba-Doo, with all of the second half dedicated to Ruby-Spears' The Puppy's New Adventures.

My Little Pony 'n Friends aired in this format. First was My Little Pony, and then one of three other shows. My Little Pony was the only segment to get aired every week. The other properties, Glo Friends, Moondreamers, and The Potato Head Kids (yes, really), alternated each week.
101 Dalmatians: The Series used the Two Shorts format most of the time.
Pepper Ann mostly uses two shorts, but there are some episodes (like "Ziterella" and "The Environmentals") where it's just one episode.
Phineas and Ferb uses a Two Shorts format for most episodes. However, there have been several full 22-minute episodes, an extended-length Christmas episode, and two occasions were the second short takes place within the same time as the first short, often to show different points of view. There have been points where the show ran in Quarter Hour Short format, mostly new shorts.
Recess follows the two shorts format, with the exception of three episodes.
Zigzagged from "played straight" to "averted" with The Ren & Stimpy Show. Some episodes had two shorts, some had two shorts and a fake commercial, and a handful of episodes (like "Son of Stimpy" and "Royal Canadian Kilted Yaksmen") don't have this format.
Rocky and Bullwinkle followed the ABCA format. The "Rocky" segments took up the beginning and the end, the B would be either "Fractured Fairy Tales" or "Aesop and Son", and C would be "Peabody's Improbable History" or "Dudley Do-Right".
Another Jay Ward program, George of the Jungle, followed the ABC format, with the other two segments being "Tom Slick" and "Super Chicken."

The first Christmas episode is a full-length episode, with the title screen popping up halfway through saying "Later That Day" and simply continuing the same episode later that same day.
A lot of specials and one-off episodes of The Simpsons are constructed like this:
The episode "Trilogy of Error" has its three seemingly irrelevant plots (Homer accidentally cutting a finger off; Lisa trying to get to a science fair; Bart and Milhouse discovering a mafia's illegal fireworks ring) become connected more and more throughout.
There are several episodes, such as "Tales from the Public Domain", "The Simpsons Spin-Off Showcase", and "Simpsons Tall Tales", which use either a Framing Device of characters telling each other stories with a Universal-Adaptor Cast, or simply Breaking the Fourth Wall, to connect them to the main continuity.
Popples is the only exception. Some tapes had up to six episodes!
The Tom and Jerry Comedy Show uses the A-B-A format. The B portion features Droopy's adventures, with Slick Wolf as the antagonist and other Tex Avery characters in supporting roles.
A later series, Tom And Jerry Kids, started off using the A-B-A format, with Tom and Jerry as the A and either Droopy or Spike and Tyke as the B. As it went on, however, the producers stopped using the format and just put together three shorts at random, though there was usually at least one Tom and Jerry short.
Daniel Tiger's Neighborhood airs in the ABAB format, with the B segments being live-action segments about kids exploring the theme of the episode, in a similar manner to the "A Word From Us Kids" segments mentioned in the Arthur examples above. Most of the time, the episodes will have the same theme. "Prince Wednesday Goes to the Potty/Daniel Tiger Goes to the Potty" and "Thank You, Grandpere Tiger!/Neighborhood Thank You Day" are two examples of this.
Jake And The Neverland Pirates aired in a three-shorts format, but unlike most shows, the B segment wasn't in the middle. Two Jake segments aired first, and the B-segment, a Neverland Pirate Band music video, aired last.
ChalkZone had a three shorts formula most of the time in an AABC format (sometimes the order of the shorts were rearranged as BAAC or ABAC depending on the episode). One A segment would be an eleven-minute story, then the commercial break, the next A segment being a seven-minute story (during the first season, these were the original Oh Yeah! Cartoons shorts, save for the first two shorts from '98 which were written into the 11 minutes as flashbacks due to the first two shorts taking place two years prior to the events of the series and the 1999 shorts), the B segment being a three-minute short starring Snap (Rudy and Penny would not appear in these shorts, nor anything involved in the real world unless the title card showed a real world character erasing the chalk drawing on the chalk board title card), and then the C segment being a one-minute music video.
A few episodes did avert the usual formula: "Double Trouble" using an AC format (the episode was 24 minutes plus the music video), three episodes ("Rudy's First Adventure/Rudy's Story", "French Fry Falls/Gift Adrift", and "The Smooch/Power Play") used the AAC format (two 11-minute episodes and a music video), one episode used a ABAB format ("Mellow Drama Falls/Snapshots II: Wild ChalkZone!/The White Board/Doofus Penny")- one eleven-minute episode, a three-minute Snap short, a seven-minute story, and another three-minute Snap short (making it one of the few episodes without a music video), one episode used an AAB format without a music video due to the B segment being a minute longer than usual ("That Thing You Drew/That Sinking Feeling/Insect Aside"), and then the Christmas special "When Santas Collide" just aired a full 24-minutes without a music video.
Kick Buttowski typically had a two-shorts format, although two episodes were full 22-minute stories and the final episode (in production order) contained three seven-minute shorts.
The first season of Toonsylvania had an ABCD format. A was Frankenstein, B was either Night of the Livijng Fred or a B-horror movie parody, C was Igor's Science Minute and D was Melissa Screetch's Morbid Morals.
Mixels: Mixed Up Special was a nine-shorts special. Seven of them were shorts that aired earlier in Mixels' first season and the other two were five- to six-minute 'minisodes' that debuted with the special.
Toot & Puddle followed the ABA format when aired on television - a story, followed by the interstitial "Boomerang Song," followed by another story. The downloads offered on YouTube are presented as individual stories. When actually aired in the three shorts format, the rule was usually if not always that one story would be about Toot (and occasionally both Toot and Puddle) traveling the world, with the other story about an adventure at home in Pocket Hollow.
The New Woody Woodpecker Show used the ABA three shorts format. The first and third shorts were about Woody while the second starred Chilly Willy instead.
Wander over Yonder tends to use the two-shorts format, with the exception seven 22-minute episodes, three in season one, and four in season two.
