Archive Panic: 189 sound cartoons alone, and 347 silent Aesop's Fables films (although how many still exist isn't known).
Big Name Fan: For the Silent-era Aesop's Fables cartoons made by Paul Terry, probably the biggest fan they ever had was Walt Disney, who saw as many of the cartoons as he could, and always wanted to make cartoons just as good as his.
Meta-example; despite never receiving an Academy Award nomination and being a virtually forgotten studio with no real acclaim going for it, "The Sunshine Makers", by sheer miracle, was nominated as a runner-up on The 50 Greatest Cartoons list.
Another real life, serendipitious moment of awesome is that in spite of how neglected the films are, virtually all of their sound films have survived the ravages of time in some form, and this allowed the studios Image Entertainment and the cartoon studio Thunderbean to go out of their way to find the best existing source material for the cartoons, and give them the best possible restoration efforts, on par with any Disney collection, and release them on home video to the public—all for what was considered a second rate cartoon studio that's been gone since 1936! And then Thunderbean announced they're giving these short films a pristine blu-ray release...
Crowning Music of Awesome: One of the best things about the cartoons is Gene Rodemich's rich musical scores. Take for instance the use of "Siamesische Wachtparade" and "Siamese Patrol" in "Toy Time" (1932), the opening Moonlight Bay number of "Silvery Moon" (1933), and the Cab Calloway-esque "Kickin the Gong Around" in "Fly Frolic" (1932). Winston Sharples would take over his position late in the studios life, and he also brought wonderfully rich music scores to his shorts.
Cult Classic: The shorts have a surprisingly large fan following for such an esoteric studio (to where an entire facebook group for the studio shares billing alongside Terry Toons), due in part to how easy its become to view all the cartoons, and the surreal, Fleischer-esque qualities of the pre-1934 shorts. Also helping is that Thunderbean has restored rereleased much of their library on DVD, and is planning on releasing them in blu-ray format as well.
Ear Worm: The cowboy song number in the Tom & Jerry short "In The Bag", especially the part where the duo starts scat singing—it will get stuck in your head.
Growing the Beard: Zigzagged. It's generally agreed that the studio made a substantial upgrade in it's production values from 1934 and onward, due in part to slicker inking, larger budgets which allowed more polished animation and an upgrade to Technicolor, thanks in part to the studio bringing in Disney alumni Burt Gillett, who had previously directed the hit short Three Little Pigs. Unfortunately, with the exception of the Toonerville Trolley shorts, the cartoons became substantially less entertaining and more derivative of Disney as a side effect, and the studios inability to create a hit character series still lingered to where they started adapting hit comic strips of the day instead (and Gillett reeked havoc on the studio internally due to his blatant personality flaws and indecisive, perfectionist directing style). And then RKO ironically cancelled their distribution contract in favor of screening the Disney shorts anyway, abruptly sending the studio to its grave in 1936.
Before Waffles and Don Dog being reinvented and renamed as the characters Tom and Jerry, Waffles (Tom's precursor) was in fact a cartoon cat, not unlike the more famous Tom Cat.
Winston Sharples was the composer for all of the Rainbow Parade cartoons, among them being the three Felix the Cat shorts made by the studio. Fast forward 23 years later, and he would become the regular composer for the Trans-Lux Felix the Cat cartoons.
Tastes Like Diabetes: A criticism of some of the Gillett era Van Beuren shorts, most notably his short lived Toddle Tales shorts and shorts like "Pastrytown Wedding".
Uncanny Valley: The clock with a real life human face in "Grandfather's Clock". It looks downright creepy!
