I still of the belief that the best sit-com of all time was Taxi. Brilliant comedy writing and acting. And patient; they didn't play every line for a laugh.
But anyone who knows me knows that I'm partial to the Jack Benny
Program. Between the radio years and television, that program ran for well over 20 years. For you youngsters or non-Americans who have no idea who Jack was, here's a clip
of Marilyn Monroe on his program (favorite part starts at 15:38). I'm told that this was her first ever appearance on TV.
