So, I’ve have this theory that the formula for classic TV is: get two dudes, one has to be blonde and the other had to be brunette. Usually the brunette is the smarter of the two, with the blonde being more “eye-candy” for the ladies. Here are the ones that fit this mold that I can remember off the top of my head:
Starsky and Hutch
Dukes of Hazzard
Battlestar Galactica
Planet of the Apes (tv series)
ChiPs
Simon & Simon
