Sanford & Son was a sitcom created from the fertile mind of Norman Lear & a hit for NBC from 1972-77. Redd Foxx plays the irascible junk man Fred Sanford, a widower who runs a junkyard with his son, Lamont portrayed by Demond Wilson who puts up with his father's shortcomings.
Fred Sanford maybe in his twilight years, but his wit is sharp enough to cut down a California redwood. Fred also has some friends like the slow-witted Grady and jolly Bubba. He also has some not-quite enemies like Aunt Esther & Rollo.
I first saw this show back in the 70's when it was rerun in the Summer on NBC & have become a huge fan since. Not all of the episodes are considered to be classic, but the show can be funny nonetheless.
