The Words, the Damn Words

Mark Twain once said that finding the right word sometimes took him "two or three days." Two or three days of staring at the wall. Two or three days of watching the baby throwing mush around the room. Two or three days of staring at the wall. Two or three days of watching the dog pee on the neighbors' lawn. Two or three days of somnambulism. Words. Did Mark Twain really say finding the right word took him two or three days? That's what I heard. From somewhere. From Wikipedia. I'm sure of it. Yup. Pretty sure.
