Apparently, the Daily News
has unlimited resources: they sent a cameraman and a chauffeur to pick up actor Jerry Stiller on Riverside Drive and taxi him to Queens to take a look at "The Costanza House"—the actual house, used in Seinfeld
for exterior shots, in which the Costanzas were supposed to have lived.
Stiller offers to knock on the door and see what happens. The first words out of the old man that lives there who answers the door? "George Costanza's father!"
It's the real life Frank & Estelle! (Except they're very friendly and polite.) Video after the jump.
