- Television
A slab of plastic with a picture on that moves. Massively influential on people's behaviour and society.

- Manholes
They're everywhere, the buggers. Nobody knows what they are for or why there are so many.

- Cakes
There is nothing else that looks like cakes, except other cakes. Cakes are an entirely man-made object, yet nobody seems to wonder why cakes look like cakes. Who decided what a cake should look like and why. Just so odd.
