I'd like to suggest a children's books theme, focused on favourite books we read as kids and how well those books stand up to reading as adults. It could also include books we read _with_ our kids, and how they got different things out of it than we did. (Keep in mind that us old folks tend to have a somewhat different definition of kids than you youngsters, so I'd suggest this scales up to at least YA.

)
What got me thinking about this was the Oz books of L. Frank Baum that I devoured as a child. We had an entire set of them that had been passed down from my father, complete with absolutely wonderful illustrations.
For a catch phrase, something along the lines of "You're never too young"
