Who could forget dialogue like this?
"What's your name?"
"...People call me 'Frog' "
"What's you're real name?"
"...Frog. That's why people call me it."
In the late '70s the proliferation of Westerns and Old-West shows came to a grinding halt as "Rawhide", "The Virginian", "Bonanza" and even "Wild, Wild West" (to name a few) lost popularity as the new generation of viewers could no longer remember the Law of the West, let alone identify with the themes.
"Best of the West" was a worthy attempt at assimilating good clean sitcom humor with glimpses of a close, but bygone era. Alas there are only so many ways to keep fresh such a plot summary before being outscripted by more modern themes (Greatest American Hero), classic "good guys always beat bad guys" shows to come like A-team, good American style fun of "Cheers", or your atypical family sitcom with a twist like "Different Strokes" and Joel Higgins' migration to "Silver Spoons".
