Question: What is the full name of the person who stole diamonds from other gangsters?  Answer the above question based on the context below:  Gerald Clamson is a bank examiner who loves fishing on his annual two-week holiday.  Unfortunately, one day at the ocean he reels in Syd Valentine (also played by Lewis), an injured gangster in a scuba diving suit.  Syd tells Gerald about diamonds he has stolen from the other gangsters and hands him a map. Gerald escapes as frogmen from a yacht machine-gun the beach.  They swim ashore, locate Syd and gun him down. Their leader Thor ensures Syd's demise by firing a torpedo from his yacht that goes ashore, blowing a crater into the beach. As the police ignore Gerald's story, Gerald heads to the Hilton Inn in San Diego where Syd claimed the diamonds were hidden.  There he meets Suzie Cartwright, an airline stewardess. While searching  for the diamonds, he needs to avoid the hotel staff after inadvertently hurting the manager. Gerald disguises himself as a character noticeably similar to Professor Julius Kelp from The Nutty Professor, while trying to stay one step ahead of the other gangsters who are on his tail, as well as the hotel detectives led by the manager—all the while courting Suzie. As each of the gangsters see Gerald, an identical lookalike to the deceased Syd, they have nervous breakdowns; one imagining himself a dog, one turning into a Larry Fine lookalike, the other (Charlie Callas, in his usual character) becoming a hopeless stutterer. The one man Gerald meets who believes him, and identifies himself as a FBI special agent, turns out to be an escapee from an insane asylum.

Syd Valentine
