Alright, I am shocked that absolutely no one has mentioned any of these shows. My favorites (all time) are M*A*S*H, Hogan's Heroes, Andy Griffith show, and All in the Family.
Even though I wasn't even born when most of these shows aired, I still enjoy catching them occasionally on TV land!
How did you get to the earth? what are you supposed to be doing here? How are you leaving?
