I don't remember the crazy colors because we had a black and white TV.
I also don't remember that Mary went braless. What a unique moment in TV history - I don't think anybody today on TV would go braless.
In this episode Phyllis asks Mary to tell her daughter Bess about sex. I don't remember that either, but it's possible that my mother made my father turn off the TV at that point. So I don't remember that Bess tells Mary that she already heard about sex, because another kid told her about it, and she didn't believe it at first.
That's how I found out about sex too - some kid in school told me, and that was my reaction too - I thought the kid made it up to gross me out. Only when I read my first adult non-fiction book Black Like Me, which describes some sexual situation (I forget what now) did I believe it was true.
