Corky Romano (2001)

A naive, bumbling veterinarian named Corky Romano, the outcast son of a Mafia boss, is recruited by his family to infiltrate the FBI and steal any and all evidence that will put his cranky father, Francis A. "Pops" Romano, in jail. But he's in way over his head when he's made out to be a super agent. It's a reputation he must live up to as he tries to fake his way through one tough assignment after another while hunting for the elusive, incriminating proof of his father's illegal activities.
