John Wheeler on The Brady Bunch

The Brady Residence

It's an odd place for a kitchen chair, but I imagine the camera dept put it there just to fill in the blank space.

I love the random appearances of The Bradys living room televison set.  Perhaps it was put there for the same reason.

Barry Williams on Here Comes The Brides 1969

Kathryn Hays 

This episode aired in January 1969, so likely was filmed sometime around the same time as The Brady Bunch pilot. Barry was certainly an in-demand, working young actor at the time!

Protesting on Classic TV

Rather than mirroring the counter culture protests of the 60s and 70s against wars, and civil rights directly, these sitcoms usually took a safer, less contoversial stance by protesting things like the closing of parks and the unfair removal of trees.

And only The Brady Bunch could march and protest without ever showing them leave the house:
