I don't know how tough it would be...maybe they have become more stringent, but the article I read way back when kind of suggested that anyone with three grand and a publicist could get a star. Oh, and they want to be assured that the recipient will show up, though I suppose that's not a strict requirement.
They could certainly be assured of a crowd, I would think, if they laid down a Bukowski star, and that's what they are looking for. A crowd and a publicity event. The Hollywood chamber of commerce is behind the stars...
