National Lampoon's Gold Diggers (2004)

Cal (Friedle) and Lenny (Owen) are two con men who dream of the fabled "good life" that includes big bucks, cool parties, fast cars and hot women, especially dream girl Charlene (Ziering). After a string of failed robbery attempts, Cal and Lenny turn to gold digging and scheme to marry the aging and inseparable Mundt sisters, Doris (Lasser) and Betty (Taylor), who the boys had met during one of their many failed criminal endeavors. Unbeknownst to Cal and Lenny, the Mundt sisters are now destitute, and are only marrying the guys so that they can knock off their young suitors and collect on their new, generous life insurance policies.
