Peter comes very drunk home late at night. He wakes his sleeping wife: “Emily wake up! You know what just happened!?”

“No”, she replies sleepily.

“I went to the toilet and the light switched on all by itself. And when I went out of there, the light switched off again without me having to do anything. I think I’m getting super powers!”

Emily replies groans: “Oh no, Peter! You pig, you just peed into the fridge again!!!”
