The first 3 seasons that ran on Fox are fantastic. Sitcoms on network tv are dead and too safe. This one did such a great job of being bigger & better than just a quirky show. Credit Ron Howard & Brian Grazer for assembling the right cast, crew & guest stars they got to be involved. For the time period there were some heavy hitting guest stars, most notably, Charlize Theron as"MR F". Ron Howard's narration was incredible. The jokes just boomerang around so well within an episode and extend to later episodes. Paying attention will payoff while watching this series as you'll laugh even more. I watched this for the 5th time and it's just an enjoyable experience each time.
