Jason Alexander Reveals Why Susan Was Killed Off 'Seinfeld'

In an interview on The Howard Stern Show, Jason Alexander revealed the real reason why Susan was killed off the hugely popular show.

It was the actress' complete lack of comedic chemistry with the Seinfeld cast that led to the death of George Costanza's fiancé.

Alexander explained that though he often had trouble finding the right comedic tone with Swedberg, his cast mates were hard pressed to believe him. It wasn't until Jerry Seinfeld and Julia Louis-Dreyfus performed extensive material with Swedberg in Season 7 that they took Alexander's concerns seriously.

"Julia actually said, 'I know, don't you want to just kill her?,'" Alexander said, which he says gave show runner Larry David the perfect plot line for his then-undecided season finale. Cut to the end of Season 7 and poor Susan dies after licking poison envelope glue.
