I was there 2 years ago and saw a homeless man walking around near the Transamerica Pyramid with dried shit on his ass. Not a just a small peice, but it was a full shit that he took in his pants, let it dry in said pants and proceeded to sag pants as well. It was a dried pancake of terd stuck to his ass. He proceeded to wipe his ass bear style on the side of a bank that was open (people walking in and out approximately 3-5 feet away). All the while, people in the city walked by like it was no big deal. It was lunchtime. The only reason I noticed was when the homeless man walked by me, I smelt shit. No one else seemed to care.
