upsidedown paw
when you're sitting on the toilet and the bathroom door is closed, and you hear scratching at the door, and when you look, there is a cats paw poking out from under the door, but its facing upwards.
When I opened the door, the cat was sitting there whistling. I asked what the paw was about, and the cat said, I saw a cat who looked just like me walking by, but he had an upsidedown paw, he said something about sticking his paw under the door, but im not sure, because i was sitting here whistling.
