There are plenty of others, but for now I'll second the honeymoon breakfast in FATTY AND MABEL ADRIFT [1916]. Often considered his best film, the scene with Arbuckle and Normand is excellent. It was praised for its direction, but Arbuckle was not singled out as the director.
In the episode SINGLE BEDS AND DOUBLE STANDARDS from the 1980 series HOLLYWOOD [narrated by James Mason[, Mason comments, "The scene is played with a warmth and charm not often found in early knockabout comedy." Arbuckle also looks straight at the camera which was unusual at the time. Arbuckle is excellent and Normand is cute.
The scene from THE ROUNDERS [1914] with Arbuckle and Chaplin was played at the start of the episode. Two of the greatest comedians of the silent era together. In fact, Arbuckle was the only one to work with Chaplin, Buster Keaton and Harold Lloyd.

Although Chaplin performed the gag much better, I still like the dance of the roles in the Arbuckle comedy

I don't know. But some of my Arbuckle favorites are 'The Rounders', 'Fatty and Mabel Adrift' and 'The Reckless Romeo'.

The bit in 'The Garage', when Roscoe is in bed, and he turns to kiss the picture of the girl on the wall that would have got a big laugh from the audiences at the time as the picture was of Mabel Normand!
And I love the dance sequence in 'The Hayseed', with Buster and Roscoe flinging that tiny woman around (who was obviously a pro acrobat or stunt performer), and Buster flinging himself around in spectacular style, as usual!
And in every scene that Luke was in (Roscoe's amazing dog), he upstaged everyone - apart from Roscoe and Buster that is!

The scene in Goodnight Nurse where Arbuckle in drag flirts with "Doctor" Keaton and keeps running his finger on the wall and then licking it. Hilarious!!
So shines a good deed in a weary world
