I just wanted to mention, I re-watched the episode, and there it was, defnitely. A guy in a big round trash can with a lid, with 2 arm holes in it. He had his arms sticking out, and had them wrapped around the front of the can, kind of.
He had a small, open-topped box lying on the ground in front of him. My wife suggested that maybe he'd found a "different" way to beg for money, by trying to be a performance artist, or making a point, or something. Who knows.
But Cali wasn't crazy after all (well, not about this!)
