The Tramp and the Dog

It is also likely the first commercial narrative film shot in Chicago.

[1] Described as a "backyard comedy" (filmed in the Rogers Park neighborhood),[1] in the opening bit, a baker comes outdoors into her yard and leaves a pie on a chair to cool.

[2] A bulldog appears who catches the backside of the tramp as he tries to escape, leading to various pratfalls, and the woman reappearing with a broom.

[1][2] The film became very popular and was distributed throughout North America and Europe.

It began a film trend known as "pants humor" where the loss or threatened loss of the character's trousers formed the gag, and it led to a number of filmmakers to feature tramps and hobos in short comedic situations.
