π
Evening conversation with my 7 y.o.:
me: Michael, tell me what's the next number after -1.
0
me: OK...
what's the next number after π?
4
Close enough as he answered after ~1 second, never even hearing about π ... unless he's secretly reading Wikipedia articles instead of playing games...
What's your interesting moment of this sort?
PS: Adam recommended me themagpi if I finally decide to show some programming to Michael (well, we started even before, with tools like repl.it).
