And that the whole family lived comfortably with Mike the architect as the sole wage earner? And nobody questioned why the three girls automatically changed their last names to Brady?
Another fun fact: Did you know that Robert Reed, the actor who play Mike Brady, was gay but kept it private, fearing it would damage his career? When he died of colon cancer at 59 in 1992, details from his death certificate were made public revealing that he was HIV positive. His doctor listed that on the death certificate as "a significant condition that contributed to death."
