Several Seinfeld cast members recorded a series of videos for a dying man, James Anthony Calder, after his son reached out to say his father was a super fan who could use a boost for his 67th birthday. He was just shy of that birthday when he passed away from a rare non-smoking form of lung cancer on November 7, 2015. But in the weeks before he died, his dedicated son James embarked on the ambitious quest to collect well wishes from the cast. And many favorites from Seinfeld delivered, making James a very happy man prior to his passing.
