How Many Psychopaths Does It Take To Change A Lightbulb?

I’m just leaning down to turn the lamp off when she speaks.

“Okay, I won’t tell anyone.”

I’m staring at the lampshade. The lampshade is meant to shade the light but the light is still getting through.

“Look here. I trust the lampshade to shade the light.”

Even as I’m telling her I can see the light shining through her eyes, like glowing fireballs. She clearly doesn’t understand what I mean; so, I show her.

I pull the plug on them both and finally, the light stops shining through her eyes.

“Now you understand.”

(None. The bulb didn’t need changing…)
