@clairemobey and I have been steadily going through many older series that were good with our kids.
Then people visit us and make some joke and turn to our kids and say "You probably don't know who that is." and they get to find out that the kids do indeed know who they are talking about.!
Some newer series smattered in there as well... its been fun.
Another thing I do from my yester-year is load up some emulators and play some of the old but awesome Nintendo games. There are some of those games that never age for me!
