In this silent film from 1899, two ladies (male actors play the parts) are engaged in some sort of excited exchange when two men play a trick on them. From the YouTube page:
The film doesn't make clear why they deserve this attack, but an accompanying set of cards produced by the production company indicates that the ladies were engaged in a discussion about the then pressing political issue of women's suffrage.

1 point for the technical feat though.
