This probably won’t translate very well into this arena, but I had to try. Here’s the scene:

I’m sitting at the kitchen table last night about 10:30p. Abby was having trouble sleeping after taking a late afternoon nap. So she’s lying in bed, humming a recognizable tune:

“Dun dun du-dun, dun du-dun, dun du-dun…”

“Abby,” says I, “go to sleep, honey.”

“Did you hear that sound?” she asks.

“Yes, honey, I heard it. Now go to sleep.”

“Do you know what that sound is, Daddy? That’s the sound Darth Vader makes! Dun dun du-dun, dun du-dun, dun du-dun…”

I laughed for four minutes.
