Okay, maybe Married with Children shouldn't be classified as 'classic' but during the years it aired I really enjoyed Al Bundy's humorous suffering and adventure.
Here's a classic clip from the show, where Al Bundy faces high school nemesis, Spare Tire Dixon (Bubba Smith). Give it a click and I hope you enjoy :)
As an additional note: Ed O'Neil, who plays Al Bundy, was a college football player, drafted by the Pittsburgh Steelers. If I recall accurately, he was the last person cut from the team during training camp in 1969.
