I loved seeing the actor who played Brock as well as the one who played Van appear on happy's place last season.
Hogans Heroes. Originally aired before I was even thought of, caught by accident when channel hopping one night and loved it.
all my dad watches to this day are 50's and 60's sitcoms.
I've often thought how if my dad were still alive he would LOVE some of the retro channels b/c he could sit for hours on end and enjoy 'gunsmoke', 'mutual of omaha's wild kingdom', 'hogan's heros' and others I vividly remember he faithfully watched.
