Well, the whole talk wasn't about this, but I remember a brother adding to his talk that sisters shouldn't wear red shoes, I think this was after David Bowie's "Let's Dance" came out ("put on your red shoes and dance the blues")
Also I remember a CO dropping into one of his talks that brothers shouldn't watch football . . . well, ya' just know all the brothers immediately stopped watching football after they heard that don't you! Bet they haven't seen a game since that talk, and that was around the time I was in Junior HIgh School in the 70's.
