The Cord May Be Plugged In, But The Brain Is Unplugged

(My brother is working very late on the computer. The cleaning lady comes in and a second later his computer turns off. She has taken out the plug to put in her vacuum cleaner.)

My Brother: “Hey, why did you pull my plug out?”

Cleaning Lady: “Vacuum cord doesn’t reach from out there. I do it every time and I always put it back in.”

Brother: “But I was never in here using the computer when you did it.”

Cleaning Lady: “Oops.”
