I'd bet the retarded fellow named Nicky was Nicky Beyer who lived on Funston, just off Taraval. He was quite a character and used to attend a sheltered workshop run by Aid Retarded Childen, later Aid retarded Citizens at 1362-9th. Ave. Dr. Eric Berne, author of The Games People Play was the staff psychologist at ARC and Nicky was one of the inspirations for the book. In spite of his apparent severe retardation, he was a sharp manipulator. His brother whom I haven't seen in a bit, is an accomplished musician and his sister (Yvonne ?) was the principal of the (High?)School of the Arts.
