in which my children make connections that would never ever have occurred to me

This actually happened in the fall, but I was reminded about it this week, so here you go.

Me: The Halloween song, "Have you seen the ghost of John" -- do you know that song?
A: No! What are the words?
Me: Have you seen the ghost of John
Long white bones with the skin all go-o-o-o-one
Wouldn't it be chilly with no skin on!
A: *thinks about this*
A: ...
A: ...Is this the same John that's in the song "Are you sleeping?"
E: Wait!! maybe he isn't hearing the morning bells ringing because he's DEAD and a GHOST!
All three of us: *laugh uproariously*
