Well not literally but there is a certain tour champ who's name I shall not say who posts vids on YouTube and putts with no putter pal (putting blind) and does it with alarming accuracy. Anyway, after watching a few of his vids I decided to have a go myself. Pebble beach, no putter pal. I was surprised how well I did, 4 over par. I was wondering if any other player does this and how well they do.
