Peter came home very drunk late one night. He woke his sleeping wife: "Emily, wake up! You know what just happened?!"
"No," she replied sleepily.
"I went to the toilet, and the light switched on all by itself. When I left, it switched off again without me doing anything. I think I'm getting superpowers!"
Emily groaned: "Oh no, Peter! You pig, you just peed into the fridge again!!!"
