Just before the "Seinfeld" series finale aired, Jason Alexander appeared on "The Howard Stern Show." He explained that due to fan interest in what would happen, only the four primary actors — Jerry Seinfeld (Jerry), Julia Louis-Dreyfus (Elaine Benes), Michael Richards (Cosmo Kramer), and he — were allowed to have full scripts. When asked if his wife was able to take a peek at the script, Alexander revealed that she appeared in the episode. When Stern asked who she was, to protect his family's privacy, Alexander simply said, "She's just my wife."
When asked why she appeared in it, Alexander simply remarked, "I requested that my wife appear in the final episode." He was further asked by co-host Robin Quivers if other spouses were on the show, and he stated that Louis-Dreyfus' sister, his parents, Seinfeld's mother, and even his high school drama teacher were all on it, many of whom appeared in other episodes over the years. Regarding Title's acting, he hilariously stated, "I have to say she's terrific because I basically ignored her and they were shooting there for three days."
To illustrate Alexander's deep love for her, when jokingly asked if he would immediately start dating if she passed away, he responded, "I could never replace my wife. Never," adding, "I would be devastated. I'd probably just have to seclude myself for the rest of my life."
