“Bird asked what a paleontologist was and Mom said that if he took a complete, illustrated guide to the Metropolitan Museum of Art, shred it into a hundred pieces, cast them into the wind from the museum’s steps, let a few weeks pass, went back and scoured Fifth Avenue and Central Park for as many surviving scraps as he could find, then tried to reconstruct the history of painting, including schools, styles, genres, and names of painters from his scraps, that would be like a paleontologist.”
