As one of the greatest sitcoms ever made, "Happy Days" seems in retrospect as if it should have been no-brainer for ABC execs (who originally wanted to give the show a hilariously bad title ). But it actually took some time for the series to make it to air, with "Happy Days" going through several iterations before it debuted in its final form. One of those was as part of the TV series "Love, American Style." ABC's comedy anthology show ran from 1969 to 1974 and comprised multiple romantic comedy tales, with several recurring performers portraying different characters. The show featured guest stars that included Diane Keaton and Harrison Ford, but it's also noteworthy for giving audiences the very first version of "Happy Days."
