“Sanford and Son” was a comedic gem that brought laughter to millions. Starring the inimitable Redd Foxx as Fred Sanford, a cranky junk dealer in Los Angeles, the show’s humor stemmed from Fred’s sarcastic remarks and his constant “heart attack” threats (“This is the big one, Elizabeth!”). The show’s unique setting and African American lead characters made it stand out, offering a slice of life that was relatable and wildly entertaining.

9. “The Waltons” (CBS, 1972–1981)
