Saturday Night Live

On October 11, 1975 at 11:30 p.m., NBC viewers who tuned in to the network's new late night show saw a sketch featuring John Belushi repeating, in a thick foreign accent, nonsensical phrases about wolverines being read to him by head writer Michael O'Donohue. Abruptly, O'Donohue clutched his heart and collapsed onto the floor. Belushi paused, raised his eyebrow, and then did the same. Posing as the stage manager, Chevy Chase entered the set and feigned confusion before breaking character and announcing to the camera: "Live from New York, it's Saturday Night!"
