"TV Couples We Wish Never Got Together" - George and Susan
"Seinfeld" contained no shortage of failed relationships, always played for comedic value throughout the series' run.
One of the show's most infamous was perennial sad-sack George Costanza (Jason Alexander) seemingly finding true love with Susan Ross (Heidi Swedberg). The couple got as far as becoming engaged, but tragedy struck when George unknowingly bought cheap envelopes for wedding invitations with toxic glue.
In one of TV's most shocking deaths ever, Susan died from licking too many envelopes as she was preparing to mail the invitations.
Alexander has alluded to Swedberg not quite fitting in with the show's main cast. This led co-creator Larry David to kill the character off in what became one of the series' darkest episodes.
Later, Alexander apologized for his comments about his perceived difficulties of working with Swedberg and her character's place in the show. But most fans would agree that George's brief engagement was an odd direction, with poor Susan Ross deserving better than she got in more ways than one.
