The Duel (1912)

A couple of French noblemen-types constantly argue (Sterling and Sennett). They're rivals for a lovely Mabel's attentions. While attending a picnic near the Hudson River (on a rather cold-looking day), She apparently favors Mack over Ford, so, obsessed with revenge as he usually is in Keystone comedies, he sets her little dog out on a raft and dares chicken- hearted Mack to rescue it.
