Amen,Bugman!Like its spin-offLaverne & Shirley,Happy Dayswas full of anachronisms,maybe worse than the former.If Chachi had actually gone around wearing shoulder-length hair parted down the middle in 1957 Milwaukee,somebody could have blown his brains out & used the hairstyle as an excuse to have it ruled a justifiable homicide.A real Howard Cunningham would have told Fonzie not to even think about talking to his family,the same would have gone for the two bimbos from that spin-off.When the show transformed the time to the early '60's,they had the girls in miniskirts & guys wearing their hair longer than the Beatles wore theirs when they came to America in 1964.The miniskirt came in late 1966 & ear-covering hair on males was not really commonplace until the early '70's.
