Know how to play chess, but don't know how to play it well (Know which piece can move where, but would get demolished in a real game)
Don't know how to play poker.
Could theoretically change the oil in my car as well as the sparkplugs (but that would require me to look stuff up first)
Don't know how to drive stick, probably will never learn.
Can handle chopsticks but not well.
Never really learned how to cook. (The first thing my mom showed me was how to clean a chicken. That made me not want to learn anything else)
The list goes on and on...
