Jason Alexander on Bittersweet "Seinfeld" Memories + Why He Gets the Flu Shot Religiously

Jason Alexander opens up about sadly losing all four "Seinfeld" parents + recalls getting the flu at 29 years old when he was in "Jerome Robbins' Broadway" on Broadway. He came down with it before a special performance for Tony voters—and he went on to get bronchitis from it. Ever since, he's gotten a flu shot every year.

"I've been getting it religiously for at least the last 20 years, maybe more," Jason says.
