The 23rd book on my Kerouac bookshelf is Jack Kerouac's Beat Generation (Thunder's Mouth Press, 2005), and the 23rd sentence (in honor of today being the 23rd day of the month) is:
Ah just what I like to see in the morning, boys and girls.
Keep in mind the mystical qualities of the number 23 (as outlined in my post from December 18, 2008 which you can read here). Mystically speaking, what is it that you like to see in the morning? Answer that and the rest of your day will be the color of golden honey.
