Mike's Horror-Scope

Air date: 1/16/70

Carol reads Mike's horoscope, which tells of a strange woman entering his life. The next day, Mike is besieged by a fussy client - Beebe Gallini - who wants her new cosmetic factory to have any sort of design - even to Mike's liking - as long as it's "Beebe" pink. The weekend comes when Mike gets a last minute phone call from Beebe with plenty of new ideas for her factory, which means he can't take the boys fishing as first planned, so Carol agrees to take the boys fishing, and arranges to have Alice take the girls pony riding. While Mike was at Beebe's apartment - also her office - sampling her cosmetics, Alice comes home from pony riding, all roughed up and sore after getting bucked off a pony, she now prefers merry-go-rounds over ponies as the girls help comfort her, and then the boys help Carol into the kitchen after she had an even rougher day of fishing, she got seasick, sunburned, caught on someone else's fishing line, fell into a pile of fish, and wants no mention made of food. While Beebe takes over Mike's office just like it's her very own, the kids are complaining to Carol they don't get to see much of their dad anymore, because he's so busy working with Beebe, and Carol's starting to complain to Mike about this as well. When Beebe visits the Brady home, she's insistent on wanting her cosmetic factory to be impossibly designed to her specifications as Mike ultimately loses the deal when she's accidentally roughed up, first by Peter, then by Bobby. Peter's model airplane is accidentally flown in from across the living room, which flies into and ruins Beebe's professionally styled hair. Bobby and Cindy are cascading water on each other with each one of their squirt guns when Bobby accidentally gets Beebe all cascaded on with water from his squirt gun, all meant for Cindy, prompting Cindy to say, "Mommy, she cries black tears." Mike realizes losing the deal with Beebe has saved his firm from a nervous breakdown.
