Logo of NBC
In 1967, NBC was the first American television network to air The Beatles' film "A Hard Day's Night"; however, as it was filmed in black and white, NBC had to temporarily replace the peacock: a caption showing "I Dream of Jeannie" and "The Jerry Lewis Show" (the programs NBC was pre-empting that night) was pushed off-screen by an animated, waddling penguin adorned with a top hat that flapped its flightless wings (imitating the peacock), accompanied by announcer Mel Brandt drolly saying ""I Dream of Jeannie" and "The Jerry Lewis Show" will not be seen tonight. Instead... (music cue) The following very, very special program is brought to you in lively black and white, on NBC." At the end of the sequence, the penguin is shown taking off its top hat and unzipping its chest, with The Beatles jumping out and performing, before running away while being chased by fangirls.
