Jerry Stiller

Daniel von Bargen

Sam Lloyd

In Elaine's extensive catalog of men who become obsessed with her, Sam Lloyd’s Ricky is one of the creepiest. Lloyd was best known for his work on “Scrubs,” and he was only 55 when he was diagnosed with a brain tumor and lung cancer, dying shortly after in 2020.
