I loved watching that show as a kid. I'm sure a lot of things went over my head, but I liked the setting and the entire cast. PS - Bailey, always (in the whole "Ginger vs. Mary Ann" thing, I always go for the smarter, more natural/grounded, girl-next-door type). Jennifer never even registered on my radar; Bailey (Jan Smithers) was right there alongside Lynda Carter, Lindsay Wagner and Erin Grey as my pre-teen, boy-of-the-70's first crushes.
Funny show, with a great cast...everyone was so different. Even as a 10-year-old, that wasn't lost on me..."he's cool, he's funny, he's nerdy, she's smart, he's wormy, he's dumb, etc." I knew what I was in for, any time one of them appeared on screen..."Mr. Carlson is going to misunderstand something, Andy has to fix it, Herb is going to get shot down again, Johnny is going to say something funny and leave the room", etc.
