At 8pm EDT. Not the 1st episode of the series Happy Days. Nope. The episode that started it all. The episode was part of the 70s anthology series Love, American Style.
I assume there are some Happy Days fans. I loved this show as a grade schooler/junior high schooler in the 70s. Tuesday night ABC of Happy Days, Laverne and Shirley, Three's Company and Barney Miller. Second greatest comedy line up ever. First was Cosby, Family Ties, Cheers, Night Court. Adding in 10pms LA Law made it the greatest night eveeer. This was 1980s all on NBC.
