I am not currently watching anything due to lack of time, but I liked several TV Shows from Discovery Channel, History Channel and NatGeo like "Gold Rush", "Bering sea gold", and also I´m very very interested about air crash investigations, like "Mayday", "Aircrash confidential" and also "Seconds from disaster".
"The Simpson´s" and "Family guy" also long time favourites.
"Married with children" is an older one that comes to mind, that can be watched again for some smiles.
