TIL that the infamous ‘Jumping the Shark’ episode of Happy Days occurred relatively EARLY in the run of the series.. all these years, i thought that the Shark episode was the death knell of the series.. but it happened in basically the fourth season of the show (in the year 1977) and there were SEVEN more years of the show after Fonzie’s shark jump.. it’s crazy how wrong my perception was, because of what JTS has come to mean .
