What's genre do you like best in classic TV?

I definitely enjoy:

Dick Van Dyke Show
Honeymooners
M.A.S.H.
Gunsmoke
Perry Mason (my mother adored him!)
Bewitched
I Dream of Jeannie
Wild, Wild West
Columbo (I like how he's scruffy, the coat & cigar, and it's always how he downplays everything and gets underestimated)
Rockford Files

I love the black & white TV the best!
