When I was a kid I was real good at shooting marbles.
But who plays marbles any more, even children?
I don't know who plays them but they have tons on sale on places like amazon. Usually listed under Games: Dice & Marbles. My guess it has become more of an indoor game over the years. That said, my niece collects marbles in glass jars for decoration.
I had mad skills dialing with my thumb on rotary phones
Marbles are also good for marble runs.

I know some too. Probably not a whole lot taken on the whole of all the commands that were available, but enough to get around and do some simple batch file scripting.
I'm one of those who has the terminal shortcut on my command bar on my Mac. Done a bit of work with various Unix/Linux/etc systems over the years so I know some of those commands as well and have done some shell scripting with those.
