The Gusher(1913)

Mabel has two suitors - an oily con man, whom she mocks in a very funny scene where she is shown twiddling a fake moustache and making her feelings very clearly felt. Even in this early comedy her natural fun comes through. The one she really loves is clumsy yokel Ford Sterling, who is determined to buy an oil well that the con man has for sale. The conman gets a local fellow to pour oil over the property. Ford falls for it and buys it - Mabel and he are to be married. Then the fellow confesses that it was just a scam - there was no oil.
