An elegant & amusing passage from Colin Ellard's You are Here:
"As legend has it, the building where I work, the psychology building at the University of Waterloo, in Ontario, was designed so that its shape corresponds roughly to the shape of a brain. Many visitors or even longtime students complain that they have difficulty finding their way about because of the lack of distinguishable landmarks in the corridors."
Do you get why that's funny? Think about it. But don't get lost.
