This guy is known was Bushman, he scares people by hiding behind an obviously fake bush that he holds in his hand (sometimes it's basically a twig) and shouts BOO at people as they get too close. It's priceless, you can usually watch him all day if you sit in the window seats at Joe's Crab Shack and look across the street.
Not sure if this guy still hangs out at the cable car turn-around, but there was an aging black dude who sat next to a sign with all kinds of claims about HIV/AIDS, gay people, religion, etc, and he'd chat with you if you asked him about it.
