In the middle of the night my son came into the room, as he does at times.  He was sleepy.  He asked me a question.

“Daddy, how come Santa never takes showers?”

“How do you know he never takes showers?”

“Because he doesn’t have a shower anywhere in his workshop.”

“I bet he does but you just haven’t seen it.  I’m sure he must get clean somehow.”

“Oh. OK”

And he went back to sleep.
