Saturday Night Live (1975)

"The Coneheads At Home," January 15, 1977 Dan Aykroyd, Jane Curtin and Laraine Newman play Beldar, Prymaat and Connie Conehead, a family of aliens with towering heads who describe everyday suburban life in stiff, overly formal language. That deadpan vocabulary is the whole joke, and it carried the family through years of sketches. This early installment, in the episode hosted by Ralph Nader, has Bill Murray as Ronnie Getsetter, a neighbor trying to take them in stride.
