For a television show about nothing, the cast members sure know how to give a little something to a dying man in celebration of his 67th birthday.

Jim Calder had been battling lung cancer for two years leading up to this November birthday. His son, James Calder, felt inspired to throw a virtual party and began asking his dad's favorite people to send in videos. Then he reached out to the actors of Jim's favorite show-Seinfeld-asking for happy birthday wishes.

Responses from the sitcom's actors poured in, including Larry Thomas, 'The Soup Nazi', exclaiming "No cake for you!" and Wayne Knight, the actor who played Seinfeld's neighbor Newman, saying a snide "Hello Jim!" in classic character.

Michael Richards, who played the eccentric Cosmo Kramer, said he wanted to make a phone call instead, while Frank Costanza, played by Jerry Stiller, sent a video but requested it only be kept private within the Calder family.

Jim's health suddenly took a turn for the worse, while the family was keeping their secret surprise-and waiting for more videos to arrive. They decided it was time for the big reveal. At the last minute, a special delivery arrived, from the one and only Julia Louis-Dreyfus, who played Elaine. In the video below, she congratulates Jim on doing such a good job raising his son. "He clearly adores you," she said within a very touching message.

"He was shocked and mystified about how we were able to reach the Seinfeld cast members," James wrote in a blog post on the Huffington Post.  "He really felt the love and support."

Jim died the next day, on November 7th, three days before his birthday. His wife said she took it as 'a sign' that one of his favorite Seinfeld episode was on television that day.
