You hear a lot about New York's "Pale Male," the bird who chose to roost in high-priced Manhattan real estate, crapping all over the wealthy residents as they stepped out onto the sidewalk.
You hear less about the literate birds of San Francisco, who have been instructed not to lay on the foundations near this sign. That's good advice. The eggs would just roll off, and perhaps splat on people as they passed.
Wait... what's that? This isn't for the birds, after all? You mean people were trying to lie on the foundations? Goodness, that sounds uncomfortable.
Thanks, Barry L., for the photo.
