The Scarecrow

This film is in the public domain and can be viewed in its entirety right here, on this very wiki.

Not to be confused with the Batman villain, the Wizard of Oz character, or the 1983 Soviet film Scarecrow.

Tropes used in The Scarecrow include:

Accidental Marriage: Sybil runs across Buster as he's getting up from tying a shoe, putting him in the classic one-knee marriage proposal pose. Cue intertitle: "This is so sudden." Luckily, he wants to marry her.
Amplified Animal Aptitude: Did that dog just climb a ladder? And descend a ladder, headfirst?
