Edna Purviance
The scene cuts towards a girl and her lover (Edna Purviance and Eric Campbell). They realize Edna's mother (Marta Golden) is drowning. They go over to help her. Edna begs Campbell to help, but he refuses because of his fatness. She jumps in, while Campbell leans against the fence and hawks at her. However, this man's sheer weight contributes to the fence giving away, and, of course, Campbell goes "ker-plam!" into the water.
