So many people don't even have televisions or TV service these days but I have fond memories. As Thomas Wolfe implied, I'm not sure if you can ever go home again...and is anything as good as you remember it was as a child? But here are some of the shows I loved: My Favorite Martian
KCLS has Saturday Night Live when it used to be good that I would leave a party to go watch it! And wasn't Laugh-in's Ruth Buzzi a precursor of Gilda Radner's Emily Litella?
Another great show that made me think life as an adult would be so cool was The Dick Van Dyke Show!
Mary and Rhoda gave me confidence to be on my own and was a great show! The Mary Tyler Moore Show
Don't see one of your favorites? Look at Encyclopedia of Television Shows, 1925 Through 2007
